Depends on the tunneling protocol you use, and on what platform you are using. For example, I use vtund package (server-client shema) with simple config to connect to my network with a "long LAN cable" going through internet and giving me access to my fully routed network with dozens of routers/hops. And only server has to have public IP with open vtund port. Once created it will reconnect if link was broken. There is also OpenVPN from more used protocol. Anly thing you need to watch for is routing, telling systems on both sides what subnets they can see on the other side of the link, but it is also part of the protocol config, or you can even use dynamic routing. If you use standalone tunneling devices, setting boils down to configuring via web config by adding parameters. Ljubomir
