I am using Snort and a few other tools to decide which I'd like best.
Here's the thing about Lowell's comment on Bridging.  Is this necessary
in this case?  I don't want the interface without an IP to EVER transmit
outbound.  If I Need to enable bridging I'll do so.  The other thing is,
is it possible to configure each card to be on a different subnet(like
xl1 on 10.X.X.X and xl0 on 192.X.X.X)?

Bpf is in the kernel
Andrew, do you like VooDoo Blue?  Let me know, I am involved.

What software are you using to sniff the traffic? Do you have the bpf 
device in your kernel? Do you get an error message or just no traffic 
recieved?

Andrew

P.S. Are you something to do with VooDoo Blue or do you just do their 
web site, or just a fan or something? :)
