There is a (very small) clue in the name: Maximum *Transmission* Unit.
Routing between two IP addresses is not (necessarily) symetric: routes
are computed independently in each direction. So there is probably a
(1320 MTU) device somewhere inbetween which is only crossed by packets
in the client->server direction, but not in the reverse.
