This article will show you how you can set up an L2TP/IPsec VPN on a Windows Server 2016 Standard with step by step screenshots. This VPN can be used to get access to your business network. We will configure the VPN with the built-in feature (Routing and Remote Access RRAS) which Microsoft is providing in Windows Server 2016.

The currently defined VPN connection settings are listed. Right click the icon you created in the previous step, and click "Properties" . On the Properties screen, switch to the "Security" tab. (In Windows XP, switch to the "Network" tab.) Choose "Layer 2 Tunneling Protocol with IPsec (L2TP/IPSec)" on the "Type of VPN" drop-down list. Setup L2TP VPN on iPhone, iPad, iPod Touch, iOS. First, touch “Settings” in Main Menu your iOS device, To setup L2TP VPN on iPhone, iPad, iPod Touch, iOS. For the VPN Provider field select Windows (built-in). Fill in each field: Connection name - Can be anything; Server name or address - This will be the public IP of the NGFW. If there are multiple public IP's this would be whatever IP address is in the Server Listen Addresses under the VPN Config tab. VPN type - L2TP/IPSec with pre-shared key L2TP Setup¶ To setup L2TP navigate to VPN > L2TP. Select Enable L2TP Server. Interface is WAN (or the same chosen for IPsec) Server Address is an unused IP address in a new subnet. It MUST NOT overlap any IP in use on the firewall, e.g x.x.x.2. Remote Address Range is the starting IP of the clients, e.g. x.x.x.128

L2TP or IPSec VPN service is built-in on some routers, the port 1701, 500 or 4500 might be occupied. To ensure VPN Server works properly, you might need to disable the built-in L2TP or IPSec VPN service through the router's management interface to have the L2TP/IPSec of VPN Server work. L2TP/IPsec¶ L2TP/IPsec is a common VPN type that wraps L2TP, an insecure tunneling protocol, inside a secure channel built using transport mode IPsec. L2TP/IPsec is supported starting with pfSense® software version 2.2-RELEASE. This article will explain how to configure the service and setup clients.
