Most interesting would probably be packet captures in both the "good" and "bad" cases; so, something like: tcpdump -s0 -wtmp.pcap then reproduce the problem, then kill tcpdump and send tmp.pcap. (And/or take a look at it yourself with "wireshark tmp.pcap", and there may be something obvious that jumps out even to a non-expert.) --b.
