Setting up Dynamic VPN where WL/IP-8000 VPN will
accept any PC worldwide from anywhere without
sacrifice security
To setup a VPN connection, it involves setting up both in the router and the
PC sides. As you will notice, the setup for the VPN server on the router is very
simple. But the setup on the client side depends on what type of VPN client
software you use on the PC. Once you take time to go through the
step-by-step example, it will become more clear and easier to setup.

EXAMPLE 1: USING IPSEC TO CONNECT 2LAN TOGETHER
Router WAN IP:
192.168.254.1 Router LAN IP: 192.168.2.254
Router LAN IP:
192.168.1.254 Router WAN IP: 192.168.254.2
PC1 IP:
192.168.1.138 PC2 IP: 192.168.2.174
USA Office German Office
In this example, we will connect the USA office and German office
together using IPSec VPN server (WL/IP-8000VPN on both sides). The
goal is to let both offices’ network together and operate as if they are on
the same LAN. PC1 can link to PC2 freely. Please note that for security
purpose, IPSec require that the IP subnet on both side of the VPN tunnel
must be different. Therefore, in this example, the USA office’s local IP
subnet is 192.168.1.x. The German office’s local IP subnet is
192.168.2.x.
