Hi Alex,

In the case you mentioned previously, does ifconfig show the interface in promisc mode? I have tried further investigating whether or not the interface is in promisc mode by using ethtool, a soft tool, however unsuccessful. I also attempted to use a hub on eth0 to see if tcpdump would pick up the packets in promisc mode; the packets are successfully captured on the hub. [I did not test eth1, but I shall tomorrow morning.] Both network interfaces are the same model/brand. Listed below is a snapshot of my ifconfig and a snippet from my lspci.

This list is pretty responsive - I just wanted to say thanks to everyone for taking time to help me out. ;)

Mahalo,
Chris

Hi Chris,

I have seen a problem with some ethernet drivers where the interface
does not go into promiscuous mode automatically as the interface is added
to a bridge.

It's worth trying to do this manually with "ifconfig eth0 promisc" and
likewise for eth1, then seeing if things work.

A few ethernet drivers don't support promiscuous mode at all.  But it
definitely looks to me the way you describe the problem that the devices
on the bridge are not in promiscuous mode.

Regards,

Alex
