Well, I have some limited IPTables rules, but nothing really special.

I'm going to look into snort_inline.  But right now, I have it on both
interfaces.  I just want to make sure that they're not going to get in
the way of each other.

Thanks!

Are you using your computer as a firewall?  If not, if you just have
the traffic coming in and going right back out, i would say, run one
instance of Snort on either interface.

Someone correct me if I am wrong.

Hey guys,

I am running snort on a computer that bridges my network.  All traffic
from the internet enters through eth0, which bridges it to eth1, which
plugs into a switch.

2 questions:
- Should I run Snort on both interfaces, or just one? If just one, which
is better, internal or external?
- Should I run Snort in permiscuous mode?  I don't see any reason to,
since neither side has a hub, but I'm just checking to make sure.

Thanks!
Ron
