Платформа Windows Server остается одной из наиболее популярных серверных платформ, в том числе и для реализации решений удаленного доступа. Служба маршрутизации и удаленного доступа (RRAS) позволяет быстро и достаточно просто развернуть VPN-сервер практически для любых нужд. Сегодня мы еще раз вернемся к этому вопросу и рассмотрим, как создать на базе Windows Server PPTP или L2TP сервер для удаленного доступа, как наиболее востребованный сценарий на сегодняшний день.
Научиться настраивать MikroTik с нуля или систематизировать уже имеющиеся знания можно на углубленном курсе по администрированию MikroTik. Автор курса, сертифицированный тренер MikroTik Дмитрий Скоромнов, лично проверяет лабораторные работы и контролирует прогресс каждого своего студента. В три раза больше информации, чем в вендорской программе MTCNA, более 20 часов практики и доступ навсегда.
Почему именно эти типы подключения? Потому что они наиболее просты в реализации и поддерживаются широким спектром клиентов что называется «из коробки». Однако следует помнить, что PPTP не является на сегодняшний день безопасным и имеет слабые алгоритмы шифрования, но при этом он наиболее производительный из VPN-протоколов и имеет минимальные накладные расходы. Кроме того, его поддержка исключена из операционных систем Apple.
Оптимальным вариантом будет использование L2TP/IPsec подключения, которое сочетает в себе простоту, поддержку практически любыми клиентскими ОС и устройствами вместе с неплохим уровнем безопасности, обеспечиваемым IPsec. А так как настройка сервера для этих видов подключений практически идентична, то мы решили объединить их в одну статью.
Установка и настройка службы маршрутизации и удаленного доступа
Для начала работы с VPN в среде Windows Server вам потребуется установить роль Удаленный доступ, это делается стандартными средствами и не должно вызвать затруднений.
В Службах ролей выбираем Маршрутизация, роль DirectAccess и VPN (RAS) будет добавлена автоматически.
После установки роли Удаленный доступ ее следует настроить, проще всего это сделать, нажав на значок с желтым треугольником в Диспетчере серверов и выбрать в появившемся списке пункт Запуск мастера начальной настройки.
В появившемся окне выбираем пункт Развернуть только VPN.
Затем в оснастке Маршрутизация и удаленный доступ щелкаем правой кнопкой мыши по строке с сервером и выбираем в выпадающем меню Настроить и включить маршрутизацию и удаленный доступ.
После чего появится хорошо знакомое окно мастера настройки, предлагающее сразу несколько типовых конфигураций, однако у него есть свои особенности, например, если у вашего сервера всего один сетевой интерфейс, то настроить вариант Удаленный доступ (VPN или модем) мастер вам не даст. Поэтому выбираем самый нижний пункт — Особая конфигурация.
В следующем окне достаточно поставить галочку Доступ к виртуальной частной сети (VPN) и завершить работу мастера.
После завершения работы мастера служба Маршрутизации и удаленного доступа будет запущена и можно приступить к настройке сервера удаленного доступа. Если же данная служба у вас уже установлена и настроена в иной конфигурации, то щелкните правой кнопкой по строке сервера и выберите Свойства, в открывшемся окне на закладке Общие установите опции: IPv4-маршрутизатор локальной сети и вызова по требованию и IPv4-сервер удаленного доступа.
Настройка PPTP и/или L2TP сервера удаленного доступа
Откроем оснастку Маршрутизация и удаленный доступ и перейдем к свойствам сервера через одноименный пункт в меню правой кнопки мыши, прежде всего убедимся, что настройки на закладке Общие соответствуют приведенным на скриншоте выше. Затем переключимся на закладку Безопасность и убедимся, что в качестве Поставщика службы проверки подлинности стоит Windows — проверка подлинности, а Поставщик учета — Windows-учет, еще ниже установим флаг Разрешить пользовательские политики IPsec для L2TP- и IKEv2-подключения и в поле Общий ключ укажите парольную фразу для предварительного ключа.
Нажав на кнопку Методы проверки подлинности откроем окно, в котором выберем только Протокол EAP и Шифрованная проверка (Microsoft, версия 2, MS-CHAP v2), остальные протоколы не являются безопасными и должны быть отключены.
На закладке IPv4 укажем опцию Назначение IPv4-адресов — Статический пул адресов и добавим новый пул для выдачи адресов из него удаленным клиентам. Количество адресов должно быть не менее количества клиентов плюс один адрес, так как первый адрес из пула присваивается серверу. Что касается самого диапазона адресов, то его выбор зависит от конфигурации сети, если вы будете использовать маршрутизацию, то он не должен пересекаться с локальной сетью, если же хотите использовать ProxyARP, то наоборот, должны выделить принадлежащий локальной сети диапазон. В нашем случае используется второй вариант.
На этом настройка сервера может считаться законченной, следующим шагом следует разрешить подключения нужным пользователям, для этого в свойствах пользователя перейдем на закладку Входящие звонки и в блоке Права доступа к сети укажем Разрешить доступ. Теперь указанный пользователь может подключаться к нашему серверу используя свои учетные данные.
Также не забудьте проверить настройки брандмауэра, чтобы убедиться, что правила Маршрутизация и удаленный доступ GRE-входящий, PPTP-входящий (для PPTP) и L2TP-входящий (для L2TP) включены.
Proxy ARP
Сетевое взаимодействие в пределах одной IP-сети осуществляется на канальном (L2) уровне, в сетях Ethernet для этого используются MAC-адреса устройств. Для того, чтобы выяснить MAC-адрес узла по его IP применяется протокол ARP (Address Resolution Protocol), использующий широковещательные запросы, на которые отвечает только обладатель указанного IP-адреса. Выдавая удаленным клиентам адреса из диапазона основной сети мы как бы помещаем их в общую IP-сеть, но так как VPN — это соединение точка-точка, ARP-запросы от удаленных клиентов в сеть попадать не будут, единственный узел который их получит — сам VPN-сервер.
Для решения данной проблемы используется технология Proxy ARP, которая, как понятно из названия, представляет прокси-сервер для ARP-запросов, позволяя удаленным клиентам работать так, как будто бы они действительно находились в одной сети, без каких-либо дополнительных настроек. При использовании RRAS никаких дополнительных действий делать не нужно, Proxy ARP работает по умолчанию.
VPN-сервер за NAT
Так как мы используем Windows Server, то с большой долей вероятности он будет находиться внутри сетевого периметра и нам понадобится настроить проброс портов на маршрутизаторе. Для этого нужно четко понимать, как работает VPN-соединение и какие порты и протоколы следует передавать.
Начнем с PPTP, прежде всего клиент устанавливает управляющее TCP-соединение на порт 1723, затем, после успешной аутентификации создается соединение для передачи данных с использованием протокола GRE.
Таким образом для работы PPTP-сервера за NAT нужно:
- пробросить порт 1723 TCP
- разрешить прохождение GRE-трафика
С первым понятно, а вот с GRE могут возникнуть затруднения. Если вы используете маршрутизатор на базе Linux, то обратитесь к следующей нашей статье, если оборудование Mikrotik, настроенное по нашей инструкции, то достаточно пробросить только 1723 TCP, прохождение GRE будет разрешено конфигурацией брандмауэра, в остальных случаях следует обратиться к документации на свою модель маршрутизатора.
С L2TP сложнее, точнее не с ним самим, а с IPsec, который не поддерживает NAT. Для обхода этих ограничений используется протокол NAT-T, который инкапсулирует пакеты IPsec в UDP, позволяя успешно проходить через NAT. Поддержка данного протокола включена по умолчанию практически во всех ОС, кроме Windows. Для включения поддержки NAT-T следует внести изменения в реестр, найдите ветку:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\PolicyAgent
И создайте в ней параметр DWORD c именем AssumeUDPEncapsulationContextOnSendRule и значением 2.
Это можно быстро сделать при помощи PowerShell:
Set-ItemProperty -Path "HKLM:SYSTEM\CurrentControlSet\Services\PolicyAgent" -Name "AssumeUDPEncapsulationContextOnSendRule" -Type DWORD -Value 2 -Force
После чего систему следует перезагрузить. Данные изменения нужно внести как на сервере, так и на клиенте.
При установлении L2TP/IPsec соединения между узлами прежде всего создается зашифрованный IPsec-канал, для этого используется протокол обмена ключами IKE (порт 500 UDP) и протокол NAT-T (порт 4500 UDP), затем уже внутри безопасного IPsec-соединения поднимается L2TP-туннель на порт 1701 UDP и происходит аутентификация пользователя.
Обратите внимание, аутентификация пользователя в L2TP, в отличии от PPTP, происходит внутри защищенного IPsec-канала, что делает данный тип соединения более безопасным.
Таким образом для работы L2TP/IPsec сервера за NAT нужно:
- пробросить порт 500 UDP
- пробросить порт 4500 UDP
- внести изменения в реестр для включения NAT-T как на сервере, так и на клиенте (только для Windows)
Вопреки распространенному заблуждению порт 1701 UDP пробрасывать не нужно.
Настройка VPN-подключения в Windows
С одной стороны это простой вопрос, с другой — имеются определенные тонкости, на которые мы как раз и обратим внимание. В Windows 10 для первичной настройки VPN-подключения служит современное приложение, которое предельно простое и не охватывает дополнительных настроек.
Поэтому после того, как вы создадите в нем подключение, следует перейти к его свойствам и на закладке Параметры — Параметры PPP установить в открывшемся окне все флажки. Это позволит использовать все возможности протокола PPP и получить оптимальное качество связи. Обратите внимание, что данные опции должны также поддерживаться со стороны сервера, в противном случае их использование в одностороннем порядке может привести к ошибкам при установлении связи.
Затем на закладке Безопасность установите в Шифрование данных — обязательное, а в пункте Проверка подлинности выберите Протокол расширенной проверки подлинности (EAP).
И наконец на закладке Сеть перейдите в свойства протокола IP версии 4 (TCP/IP 4) и нажмите Дополнительно, в открывшемся окне снимите флаг Использовать основной шлюз в удаленной сети, в противном случае весь исходящий трафик будет направлен в туннель.
После чего можем подключаться и пробовать получить доступ к ресурсам удаленной сети, если вы все сделали правильно, то проблем возникнуть не должно.
Настройка VPN-подключения в Linux
В данной части нашего материала мы будем рассматривать настройку клиентских Linux-систем при помощи графического окружения и Network Manager, настройка серверных систем выходит за рамки текущей статьи. В качестве примера мы будем использовать Ubuntu, но все сказанное будет справедливо для любых основанных на Debian систем, а с некоторыми уточнениями — для любых дистрибутивов.
Поддержка PPTP присутствует практически в любом дистрибутиве по умолчанию. Достаточно перейти в Настройки — Сеть и добавить новое VPN-подключение.
Заполняем основные настройки: адрес сервера, имя и пароль пользователя.
Затем нажимаем кнопку Дополнительно и в открывшемся окне в разделе Аутентификация оставляем только MSCHAPv2, обязательно включаем Использовать шифрование MPPE и выбираем ниже 128 бит (наиболее защищенное), также устанавливаем флаг Включить Stateful Encryption для уменьшения накладных расходов на шифрование. Флаги сжатия оставляем включенными.
Закрываем данное окно с сохранением данных и переходим на закладку IPv4, где в разделе Маршрутизация устанавливаем флаг Использовать это подключение только для ресурсов этой сети, в противном случае в туннель пойдет весь трафик узла.
На этом настройка подключения завершена, можно подключаться.
Для работы с L2TP потребуется установить дополнительные пакеты:
apt install network-manager-l2tp-gnome
После чего в доступных типах подключения появится L2TP. Основные настройки ничем не отличаются от PPTP, также адрес сервера, имя и пароль пользователя.
Затем откроем Настройки PPP, в разделе Аутентификация также выберем только MSCHAPv2, а вот опции шифрования оставляем выключенными, так как чистый L2TP шифрования не использует, для защиты канала здесь применяется IPsec. Флаги сжатия также оставляем установленными по умолчанию.
Затем переходим в Настройки IPsec, это наиболее сложная и ответственная часть настроек, так как от них напрямую зависит безопасность соединения. В поле Pre-shared key введите Общий ключ, а ниже потребуется указать используемые шифры. Большинство материалов в сети интернет копируют друг у друга откровенно старые и слабые наборы шифров, что не соответствует реалиям сегодняшнего дня, хотя соединение с такими значениями будет работать. Мы же будем использовать максимально безопасные значения, для этого в поле Phase1 Algorithms укажите aes256-sha1-ecp384, а в поле Phase2 Algorithms — aes256-sha1.
Также имеет смысл установка флага Enforce UDP Encapsulation, который принудительно включает NAT-T, в случае если вы точно знаете, что ваш сервер находится за NAT, без этой опции протокол включается автоматически при обнаружении первого устройства с NAT.
Сохраняем настройки и переходим на вкладку IPv4, где также в разделе Маршрутизация ставим флаг Использовать это подключение только для ресурсов этой сети, чтобы направить в туннель только трафик для сети офиса.
На этом настройка закончена, можно подключаться.

A Virtual Private Network (VPN) is used to securely create a tunnel for data between your local computer to a remote server. On Windows Server 2019, you can configure a VPN to provide network access to connected clients and allow connected devices to communicate securely.
This guide explains how to set up a fresh Windows Server 2019 as an L2TP over IPSec, or a PPTP VPN, using the routing and remote access feature. Layer 2 Tunneling Protocol (L2TP) with IPSec offers robust encryption for connections to the server. On the other hand, the Point to Point Tunneling Protocol (PPTP) is simple to deploy but not as secure.
To set up the VPN server, we shall use the built-in Routing and Remote access feature, which offers a graphic interface to configure remote networking features such as Dial-up, LAN routing, NAT, and VPN.
Requirements
-
Deploy a Windows Server 2019 Instance on Vultr
-
Remotely connect to the server and log in as an Administrator
Create a New VPN User
For the VPN service to work well, it must authenticate with a valid user account to the server. So, you need to create a new user on the server.
Click Tools under server manager and select Computer Management from the drop-down list to create a new user.
Once the computer management window pops up, expand Local Users and Groups from the left pane and right-click Users to select New User on the sub-menu.
Under the New User dialog box, enter a username, full name, and password for the VPN user, then click create and close the window.
The new user will now be listed on the list of active server users, right-click on the new user and select properties.
Under the user properties window, navigate to the Dial-in tab and click Allow access under Network Access Permission. Click OK for changes to take effect.
Install the Routing and Remote Access Features
Procedure 1: Through Server Manager
From the Windows start menu, open Server Manager, click Manage, then select Add Roles and Features from the drop-down list.
From the open window, click next and select Role-based or feature based installation, then select your server from the pool. Select Remote Access, Remote Access Administration from the list of server roles.
Next, select DirectAccess and VPN (RAS) and Routing from the features list, then click to Install IIS, which is required for remote access to work well.
Procedure 2: Using Windows PowerShell
You can also install Remote Access from Windows Powershell.
From the Windows start menu, open an Administrative Powershell, then install Remote access by pasting the following code to the console.
Install-WindowsFeature RemoteAccess
Install-WindowsFeature DirectAccess-VPN -IncludeManagementTools
Install-WindowsFeature Routing -IncludeManagementTools
Your output should be similar to:
PS C:\Users\Administrator> Install-WindowsFeature RemoteAccess
>> Install-WindowsFeature DirectAccess-VPN -IncludeManagementTools
>> Install-WindowsFeature Routing -IncludeManagementTools
Success Restart Needed Exit Code Feature Result
------- -------------- --------- --------------
True No Success {Remote Access}

Configure Routing and Remote Access
Open Server Manager and click Tools on the top toolbar. From the drop-down list, select Remote Access Management.
In the open Routing and Remote Access window, right click on your server name just below Server status, then select Configure and Enable Routing and Remote Access from the drop-down menu.
Now, select Custom configuration to configure remote access manually.
Select VPN Access and NAT as services you want to enable on your server, click next to finish the configuration, and start the service.
Setup a PPTP VPN
Now that Remote Access is running, you can set up your PPTP VPN. To get started, you must assign connected clients** static IP Addresses to avoid possible connection issues. To do this, right-click on your server under the Routing and Remote Access window and select Properties from the drop-down list.
Click IPV4 in the Open Window, then select Static address pool. Now, click Add to craft a new IP Address range from the open pop-up window. In this guide, we use the range 10.0.0.1 to 10.0.0.50, and the server will automatically calculate the number of available addresses.
Click OK to save your static IP Address configuration. You will be prompted to restart Routing and Remote Access for changes to apply; simply click OK.
Configure NAT and enable PPTP
We need to configure Network Address Translation (NAT) for connected clients to use the Internet. On the left pane of the same routing and remote access window, expand the IPv4 options under your server. Right-click on NAT and select New Interface.
Under the open dialog window, select Public interface and enable NAT on the interface.
Next, navigate to Services and Ports and click VPN Gateway (PPTP) from the drop-down list.
Click Edit to set a Private address for the VPN service, change the current address 0.0.0.0 to 127.0.0.1, and click OK to save.
Finally, click OK to save all changes, then right-click on your server from the left pane and click Restart under the All Tasks sub-menu.
This will restart routing and remote access services making your server ready for incoming VPN connections.
Configure Windows Firewall to accept Incoming PPTP VPN Connections
Click Tools from the Windows server manager and select Windows Defender Firewall with Advanced Security from the drop-down list.
Under the open Windows Defender Firewall with Advanced Security window, select Inbound Rules on the left pane, then click New Rule on the right pane.
In the open new Inbound rule wizard, click Predefined and select Routing and Remote Access from the list.
Under predefined rules, choose Routing and Remote Access (PPTP-In), click next to allow the connection, then finish for the new Firewall rule to be applied and test your new PPTP VPN server.
Test your PPTP VPN
Using your personal computer (PC) or Smartphone, go to Networks, Add a new VPN and select PPTP as the VPN type. Then, enter the VPN username and password created earlier to connect.
In this guide, we cover and test the PPTP VPN on a Windows 10 PC. To get started, click the start menu and search for Control Panel, then, click Network and Internet.
Under Network and Internet, open the Network and Sharing Center and click Set up a new connection or network.
Under the open window, select Connect to a workplace and click Use my Internet connection (VPN).
Then, enter your server’s public IP Address (Check your Vultr server dashboard), assign the connection a name, and click create.
Now, on the left pane, click Change adapter settings, then right click your created VPN interface and select Properties.
Under the pop-up, click Security, then choose Point to Point Tunneling Protocol (PPTP) under Type of VPN.
Finally, under Allow these protocols, select CHAP and MS-CHAP v2, then click OK to apply changes.
Your new VPN is configured successfully. Click the network connection icon on the taskbar, select your VPN on the list and click Connect to enter the VPN username and password created earlier to establish a connection to your new PPTP VPN server.
Setup L2TP with IPSEC
Open server manager, click Tools, and open Remote Access Management, then right-click your server on the left pane to select Properties from the drop-down list.
Under server properties, navigate to the Security tab, and click Allow custom IPSec policy for L2TP/IKEv2 connection to enter your new pre-shared key.
In this guide, we use 12345678, choose something stronger, then navigate to IPV4 to set a static address pool and click OK to apply changes.
Keep note of the pre-shared key (PSK) since it will be required for every user establishing a connection to the VPN server.
From the left pane, expand the IPV4 sub-menu and right-click on NAT, then select New Interface. If you set PPTP earlier, click NAT and edit the existing interface you already created.
Navigate to the Services and Ports tab and select VPN Gateway [L2TP/IPSec], then click edit to change the private address from 0.0.0.0 to 127.0.0.1. Click OK to save changes and restart remote access from the left pane under All Tasks.
This will restart Routing and Remote Access, then save the applied L2TP configurations.
Allow L2TP Connections through Windows Firewall
Open Windows Defender with Firewall, select inbound rules and add a new rule. Select Predefined and from the list, choose Routing and remote access.
Under Predefined rules, select Routing and Remote Access [L2TP-In] and click next.
Finally, allow the connection and click Finish to apply the new Firewall rule.
Connect and Test Your L2TP VPN server
In this guide, we test the new L2TP with IPSec VPN on a mac. To get started, open System Preferencesand click Network.
Under the Network Preferences window, click the + sign and select VPN under the Interface dialog box. Then, choose L2TP with IPSec as the VPN Type and assign your connection a name.
Click create, then enter your public server IP Address (server address) and username (Account name). Next, click Authentication Settings to enter your account password and Pre-shared key (Shared secret) created earlier.
Next, click Advanced and select Send all Traffic over VPN Connection, then click Apply, and finally click Connect to establish a connection with your new L2TP VPN server.

View Larger Image
In this blog article we are discussing about How to install and configure a VPN on Windows Server 2019 using Routing and Remote Access server role. A VPN is short form of virtual private network, which gives us a privacy, anonymity and security over public internet. A VPN service masks our ISP IP so your online actions are virtually untraceable. A VPN can also be used to connect computers to isolated remote computer networks that is usually inaccessible, by using the Internet or another intermediate network. Another Use of VPN is the client computers can browse websites through VPN server even if they are in the restricted internal network.
Routing and Remote Access Service is a Windows proprietary server role, that supports remote user or site-to-site connectivity by using virtual private network (VPN) or dial-up connections. So using RRAS we can convert a regular Windows Server as VPN server. Microsoft RRAS server and VPN client supports PPTP, L2TP/IPSec, SSTP and IKEv2 based VPN connection.
By default the VPN connections are made using PPTP which is a VPN Point-to-Point Tunnelling Protocol. We can also convert our VPN server to support SSTP. The PPTP protocol connection are established over TCP port 1723. PPTP also uses GRE and it supports encryption keys up to 128-bits. PPTP is a very fast VPN protocol and very easy to setup. Its supported by most operating systems like windows, Mac and Linux PC and android and IOS mobile devices.
System Configuration We Used.
Used Windows server 2019 which is covert as a VPN SSTP server.
Used Windows 10 client PC for connecting to Windows VPN server 2019.
Another thing is we are settings up VPN on windows server 2019 which only have one Network interface and its configured with Static Public IP address not NAT enabled. So this blog article can be implemented on Most of VPS ( Virtual Private Server) provided by Hosting Providers or with the Cloud Windows VMs.
Since its a VPS server, we only have RDP access using the VPS public IP address. So lets get started.
Here I have divided the whole steps in to different parts. Lets get started. Even though we are performing the install on Windows server 2019, you can refer this article for Windows server 2016 and windows server 2012.
Part:1 Install Remote Access Server role on Windows Server 2019
Log into the Windows Server 2019 > Click Windows Start Icon >> Click Server Manager.
Click Add Roles And Features
Click Next
Choose the Installation Type as ” Role based or feature based installation and click Next.
From Server selection, choose “select a server from the server pool” and click Next.
From Server Role choose ” Remote Access” and click Next.
Leave Features section as it is and click Next.
Click Next on Remote Access section.
Under Role Services choose “Direct Access and VPN (RAS) and Routing and click Next. A popup window will appear for confirming the features that need to be installed for Direct Access and VPN. Confirm it by clicking “Add Features”.
Under Web Server Role (IIS) Section click Next.
Under IIS Role services section leave the default one and Click Next.
Under Final Confirmation section click Install.
The Remote Access server role install will start automatically and normally it will get completed with in few Minutes. Once the installation succeeded click close.
Part:2 Create Additional Loopback Network Adaptor On Windows Server 2019
Its for skipping the error while running Configuring Remote Access Wizard and the error will be like below.
Less than two network interfaces were detected on this machine. For standard VPN server configuration at least two network interfaces need to be installed. Please use custom configuration path instead.
Under Server Manager click Tools >> Computer Management.
From Computer Management window Click Device Manager >> Click VM name from Right side.
Under Actions tab >> Click “Add legacy Hardware”
A add Hardware wizard will open and click Next.
Choose option ” Install the hardware that I manually select from a list ” and click Next.
Choose “Network Adaptors” and click Next.
Choose “Microsoft” as Manufacturer and ” Microsoft KM-TEST Loopback Adaptor ” as Model. Click Next.
Confirm the Install by clicking Next.
Once the install got completed close the install wizard by clicking Finish.
Now, we can confirm the new network adaptor install from the Computer Management panel itself. For that click Device Manager >> Click VM name >> Expand Network Adaptors, there we can see the newly added LoopBack Network adaptor available.
Part:3 Configuring Remote Access Service on VPN Server.
From Server Manager Choose Remote Access >> Right click the Server name >> Choose Remote Access Management.
Under “Direct Access And VPN” Click “Run the Remote Access Setup Wizard”
The Configure remote Access wizard will open Click “Deploy VPN only”
In the Routing and Remote Access Console , right click server name and choose ” configure and Enable routing and remote access ” option.
Click Next on Routing and Remote access server setup wizard.
Choose Virtual private network( VPN) access and NAT option. Click Next.
In the select Network Interface section, choose the network adaptor where our public IP configured and click Next.
In the IP address Assigned section, choose ” from a specified range of address” and Click Next. Here we are trying to define the private IP address that server give to remote VPN click PC after successful connection.
Click New button.
Give the starting and ending private IP range in the corresponding fields. Click Ok. We are giving IPs starting from 192.168.3.150 to 192.168.3.160.
Now we will see the assigned range and click Next.
In the Do you want to setup this server to work with a radius server question section, select “No, use Routing and Remote Access to authenticate connection requests” and Click next.
Click Finish on Completing the Routing and Remote Access server setup wizard.
Click Ok.
This completes the configuration of Routing and Remote Access Server. Now we can see a green up arrow next to server hostname and which shows the Routing and Remote access server service started successfully.
Part:4 Allow Remote Access to our VPN server through Public Network Adaptor.
For maintain the access to the VPN server over remote desktop we need to allow the remote access port over our public network adaptor itself through routing and remote access properties section. Otherwise we will loss the access to the server through remote desktop because we only have one Network interface available on server for both VPN traffic and for the remote access.
In the Routing and Remote Access Manager , Expand Server name >> Expand IPv4 >> Choose NAT >> Right Click Our Public Network Adaptor and choose Properties.
Select ” Remote Access” , A pop up window will appear, in the Private Address filed give our server public IP address and click OK. After that click Apply and OK.
If you have different RDP port, you need to create a new allow rule by clicking add option.
Part:5 Allow VPN remote access for the Users.
In this part we are giving a existing user on VPN server for remote access. Then only if we give the logins of these server users to remote VPN clients, they can successfully connect to server through VPN.
Go to the Computer Management Section >> Expand Local users and Groups >> Choose Users >> Right click a user where we wish to give VPN access and choose properties.
Under “Dial- In” tab >> Choose “Allow Access”. Click Apply and Ok.
Part:6 Allow VPN ports on Windows Firewall.
In this part we are allowing the ports used by the VPN server for communication on windows firewall. Otherwise the remote VPN clients won’t be able to communicate with the VPN server. Below are the ports we need to allow in VP server firewall.
- For PPTP: 1723 TCP and Protocol 47 GRE (also known as PPTP Pass-through
- For L2TP over IPSEC: 1701 TCP and 500 UDP
- For SSTP: 443 TCP
Now issue below power shell commands to allow ports in windows firewall.
Now if we look at the windows firewall inbound section , we can see the ports are allowed.
This Completes the PPTP VPN server setup on Windows server 2019. Now Lets Proceed with the Remote VPN Client on Windows 7 PC setup and Try to Establish a VPN server connection.
Step:7 Test VPN Connection.
Open Network and Sharing Center of your local PC/Laptop. Click on ‘Set up a new Connection or Network‘. Please note the screenshots are from a Windows 7 PC.
Click on Connect to a workplace.
Click on Use my Internet connection (VPN)
Enter IP address of VPN server (External network’s Primary/static IP which has Internet connection) and click on next.
Enter the user login details of VPN server, the user we created in VPN server or existing one with enabled VPN access and click on Connect.
Now you can see the client machine is trying to connect to the VPN server. Normally the connections are established using PPTP protocol. After successful connection, you can see a new VPN network adapter is created in Client PC Network adapters section.
If you right click on the VPN Network adapter and select “Properties” , you can see many tabs with different settings. Below are the default settings of my Client PC VPN network Adapter.
Refer below screenshots if you have any issues with VPN connection from client side.
Two other ways to confirm the VPN connection is successful is go back to VPN server 2019 and Open Routing and Remote Access Manager >> From there Expand our server name >> Choose Remote Access client, and in the right side we can see a active connection.
Another option to confirm the successful VPN connection is , open a browser in Windows 7 PC and search the what is my IP and it will show the public ISP IP as VPN server IP. Which means all the internet traffic from client side is routing through our VPN server.
This Concludes the settings up PPTP VPN on Windows server 2019. I hope this blog article is informative. Leave your thoughts in the comment box.

December 3, 2021 at 7:54 pm — ReplyHi,
How do I set this up with machine that is behind our company firewall and is configured with private IP address (access to internet and internal resources). So, basically I can’t configure public IP on this server, we need to use NAT, Firewall public IP -> Windows VPN server private IP. Also, can I use any private IP address for “Address range assignment” or do IPs need to be in the same network as the servers NIC? Thanks, 1st time trying to set this up.-
admin
December 3, 2021 at 8:48 pm — Replyokay, try to choose your private interface which is connected to your Firewall public IP while selecting interface and see if that works.
Also you can use any private IP range in the IP address Assigned section.
