If packets are falling on the floor then we need to know why.

Sure thing, I guess that's just another data point that Realtek
chipsets aren't the best thing to be using these days, seems
flaky.
glad it was an easy fix(this time..).

Do you see anything in the lines I pasted above? Those are the only

Well, perhaps I did not test everything out with the good card. MIght

When I switch the cards around, the addon card attached to my

next 488ms! This i

I am attempting to build an IPv4/IPv6 router. I have put a 2nd ethernet
card in a box.
I have one Ethernet card attached to my network and the other to a
switch with nothing else there just so the link comes up for testing.
When I have the built-in Ethernet attached to my network, I get ping
15 matches
