Here is how to create a basic L2TP VPN tunnel.

This example uses the following settings in creating a basic L2TP VPN tunnel.

Figure 135   L2TP VPN Example

• The ZyWALL has a static IP address of 172.16.1.2 for the ge2 interface. 
• The remote user has a dynamic public IP address and connects through the 

Internet. 

• You configure an IP address pool object named L2TP_POOL to assign the 

remote users IP addresses from 192.168.10.10 to 192.168.10.20 for use in the 

L2TP VPN tunnel. 

• The VPN rule allows the remote user to access the LAN_SUBNET which covers 

the 192.168.1.x subnet.

Click Configuration > VPN > Network > IPSec VPN > VPN Gateway to open 
the screen that lists the VPN gateways. Double-click the 
Default_L2TP_VPN_GW entry.
