Hopefully someone has had this problem and knows of a solution...
I have a Dell Poweredge 2650 (Gentoo) with 2 onboard gigabit nics (eth0
(192.168.0.1) and eth1 (192.168.1.1)), it also has a PCI 3com 905C TX 10/100
nic which is eth2 (192.217.247.61)
My problem... I cannot get this machine to connect to the internet via eth2.
It needs to use eth2 as 0 and 1 are onboard gigabit which I use for a local
NFS network. I know for 100 % certainty that all of my hardware is good and
functioning. I installed Gentoo using the eth2 3com nic off the Live CD with
no problem connecting to the internet. I have tried a different patch cable
which I knew was good (works fine on another server) and also other switch
ports I know for sure work with other servers).
My gateway for the internet is 192.217.247.1 (and this is set as the default
gateway on eth2). The LEDs on the nic are lite green, and the switch port is
also green and in forwarding mode (just like all the other ports on the
switch with servers connected). The port speed is set for auto (I have tried
100 full duplex and 100 half duplex as well and with and without flow
control).
Below are my attached config files and console outputs.
Thanks
Ryan

This is a comparison of 2 Gentoo boxes, one works fine with 2 nics, and then
is my box in issue with 3 nics that does not work.
This one works fine
