Creating an IPSec Group VPN Tunnel on a Linksys Gigabit VPN Router

A Group VPN Tunnel allows a group of users to connect to a single VPN Tunnel simultaneously.  It is recommended to use this option when your remote computers are behind a router or NAT Firewall.

NOTE:  To accomplish this setup, your VPN router must be on a different LAN IP address than the remote routers (similar to the illustration below).
