I am looking for a possibility to create an
encrypted bridge over Internet? The difference compared with "usual" VPN:n would
be that you wouldn't have to adjust routings i.e. the machines on both LANs
would be fooled to think that they exist in the same LAN. I think this to work
would need the VPN to transfer multicasts/broadcasts and whatever.
The question is: what possibilities there are
to accomplish this? Can it be done using OpenVPN?
