I would like to join two networks together using a host to lan VPN and a pair of ZeroShell routers. The host would be a ZeroShell router with a 3G USB adapter in it. The host does not have a public IP address but the server does. I would like to use the tunnel to remotely maintain the host that uses the 3G connection.
Is it possible to use ZeroShell as a host (other than LAN to LAN)? Is there documentation showing how to make this work? Does LAN to LAN have to have two public IP addresses?
