Such that after the tunnel setup the inside machine appears to be virtually attached to the remote net. Requirements: -As it is implied, I don't have administrative control over the NAT (otherwise e.g. i could simply attach the client beyond it and use `oridnary` IP tunneling) -The tunnel is encrypted (overhead issues irrelevant for the time being) -The tunnel is set on-demand, in a client-server fashion (e.g. tunneling over a TCP connection). -The operating system: Linux
