That was it! The hub is a netgear 10/100 auto
sensing hub. I'm not sure why this would affect
the traffic like that but it did. Specifically
its a DS104.
I found an old 10baseT hub. Plugged both systems
in and viola! It worked. Thanks for your time.

Subject: Re: [Snort-users] Snort
Have you tried running snort on your firewall
box? Are the results the same?
If you have a hub with learning/bridging
capability, then traffic
destined to the IPs behind the firewall will
never reach your snort box,
even tho snort puts the NIC in promiscuous mode.
Is it possible that the only traffic seen by
snort in sniffer mode is
true broadcast traffic?
(That will definitely be seen by the snort-box,
but it will probably
generate no alarms.)
