I'd get a network analyser and start looking at the packets to
find out who is the guilty one. For example I have seen client
systems choke on maximum sized packets (older Trumpet stacks with
TCP MSS=1460). Depending on target or intermediate systems MTU
and/or MRU negotiations this eventually lead to symptoms similar
to yours.
