Description Justo Alonso Achaques 2000-05-30 09:48:11 UTC
I have two 3c509B netcards. The module load ok, and with ifconfig
  I see the cards ok.
  Well, I can't ping to the nets (for none of the interfaces), except
  when I delete the default route. When I do, the net work fine!!!.
  I don't understand it.

This is no iproute problem, but a more correct package can't be known.

Please test with 'tcpdump -n' first, then run 'ping -n' to check what's there to be seen
about network.

-n is critical as if DNS servers aren't reachable, network connectivity might appear to be
broken.

Are you using a switch or hub to connect the network cards to?  Are they in autonegotiation mode?  If not,
has the network card settings been changed in /etc/conf.modules?

As no more information was provided over a long period i'll close this bug as
'WORKSFORME' as we have working setups with more than 1 ethernet card.

Read ya, Phil
