Figure 135 L2TP VPN Example

172.16.1.2

L2TP_POOL: 192.168.10.10~192.168.10.20

LAN_SUBNET: 192.168.1.x

•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.
