I'm coming to this thread a little late, so I apologize if this
information has already been passed around.

Can you provide ifconfig -a, netstat -m, netstat -s, netstat -rn output
on the troubled system.


ifconfig -a:

(note the sis0 has no configuration in the system we are talking about,
that's the working test card I installed, and what I'm using with Freesbie,
as it doesn't seem to know about the nve0)

Lots of copying and pasting. Let me know if you have any questions about
anything else, but I think I explained the only thing that looked strange
(so maybe if there's something else strange, that's my problem....)
