The number of interfaces does not matter, it does it all the time.

OK, that eliminates that then.

Which stack are you using? OpenBSD or Freebsd? Did you use template
net or new_net?

So there are no retransmits or lost packets? www.tcptrace.org is a
good tool for looking at TCP flows. Lost packets can have a big impact
on performance so first make sure this is not happening.

I suppose something else to check is the information returned from
DHCP. Is the netmask, default router, etc correct?
