The addresses of the point-to-point interface aren't local to the box, the encapsulation ones are. I do this all the time with gifs and tuns, and it works fine. Anyway, I tried it with two machines, and I see the same thing happening: Ping packets originating on the client make it over the TCP tunnel, and the server sends something back (ICMP reply, I from the looks of it). However, the data gets dropped somewhere after the bpf dumps the packet. Ping packets originating on the server never enter the tunnel, and I see "ping: sendto: Socket is not connected". A UDP tunnel (like in your example) works fine between the same machines using the same addresses. Please let me know if there's anything I can do to help track this down.
