L2TP Settings

What is L2TP?
L2TP stands Layer 2 Tunnelling Protocol and is used specifically for Mobile VPN connections.

It is highly recommended to use L2TP when using Mobile VPN for security reasons. Also, if you wish to have more than one computer connected to your XGate using your Mobile VPN connection you must set up your L2TP settings.

Analogy
Using the draw bridge analogy, using L2TP would be similar to covering the bridge (VPN Connection) with a giant pipe or tunnel. It would be impossible to see who is walking across the bridge and impossible to access the bridge outside the start and end points of the bridge.

L2TP Settings
There are two sections that you need to complete when configuring L2TP: the L2TP server settings and the L2TP user accounts.

The L2TP server settings are made up of the following details:
Server IP address
This will be the LAN IP address of your XGate.

Start IP Address
This is the first IP Address that will be allocated to the Mobile User connecting to XGate.

End IP address
This is the last IP Address that will be allocated to the Mobile User connecting to XGate.

Notes
- Ensure that the start and end IP address must  be within the network range of your XGate LAN IP (192.168.2.1 by default).
- Ensure that the range of IP Addresses between the start and end IP address do not overlap with the DHCP Server range otherwise you may have IP address conflicts.

The L2TP User accounts require the following details:
Username
The username the account holder will use when logging in to the VPN server.

Password
The password of the account holder will use when logging in to the VPN server.
