.B MTU issues:
Some relaying DNS servers enforce a 512 byte packet limit. All larger packets are
simply dropped. If you can ping through the tunnel but not login via SSH, this is
most likely the case. Set the MTU on the server to 220 to ensure that all packets
are less than 512 bytes. This will however greatly affect performance.
These issues should be solved now, with automatic fragmentation of downstream
packets. There should be no need to set the MTU explicitly on the server.
