Sorry for my late reply, I appreciate your quick answer.

I needed to get something running quickly so I dropped back to one card, and
haven't tried this again.  Next week I will have some more time to troubleshoot
this again.

I would agree that it should be a no-brainer, and I was expecting just what
you described, that I should be able to ping each interface from its own subnet.


With PNP ISA cards, (which I am using for one interface 3c509) I booted DOS
and configured the card for PNP.  I was going to try to hardcode the address
and irq in the kernel conf file to see if that makes any difference.

Regards,

Doug Egan
