I'm setting up ipip tunneling between five servers - that is, four tunnels in total going to one machine. Is it possible to have just one tunneling device on this one machine? Right now I've got one device per tunnel. Well, if you've got four different destinations, you'll need some way to route to them. How would you do that with only one device?
Wouldn't plain routing take care of that? When I have a VPN set up with openPVN, I only have one tun0 device on the server.
I also use OpenVPN. Now, assuming you've sent the data to tun0, how does it get routed to the appropriate computer? When you use a tunnel, the original IP address is no longer visible to routers, so routing has to be done, prior to that point.
