Snort + iptables

Hi gang,

Given a home user's situation (or at least this particular home user's
situation), I have a single point to the outside world, a Linux firewall
running 2.4.5. and iptables.

I am currently on cablemodem (but when I move, its to dialup country). Its
not really feasable for me, especially on a dialup, to place a Snort sensor
on the outside of the firewall.

I know that Alexander Newald has written Snort2IPTables, but I am less
interested in an automated response than I am in capturing packets in my
snort db. Is there a way to assimilate iptables logs into the Snort
databese? I use gShield and a very restrictive ruleset, and I would like to
also see the things that iptables/gShield is dropping. Is there a way to do
this?

N.B. Jim, beat ya to the punch. :)

Thanks,
--
