Promiscuous mode on only one interface

["Brei, Matt" <mbrei () medclaiminc com>]

Greetings,
 
I am using snort 1.9.1 on Red Hat 8.0.  The machine has 2 NICs, one for
Internet and one for LAN, and is running an iptables script to route and
firewall the connection to the Internet.  Everything is working great,
but I can't get snort to listen on both interfaces.  I would like to see
what snort picks up before the firewall has a chance to drop it.  I'm
not sure if it has anything to do with it, but eth0 (LAN) is the only of
the two that runs in promiscuous mode.  Any advice would be appreciated.
 
 
Matt
