rc.firewall script problems

Hello everyone,
My rc.firewall (an exact copy of
http://www.honeynet.org/tools/dcontrol/rc.firewall, except for some
configuration options) does not work properly. The firewall doesn't log
anything or allow any connections outbound. After a lot of tinkering, I
discovered that the -i flag used to specify interface does not seem to be
working at all. If I remove the -i flag then the firewall sort-of works (the
firewall assumes everything is INBOUND because the inbound lines preceed the
outbound lines). My kernel is 2.6.11.3 and has every netfilter option
enabled. I have rebuilt iptables several times to no avail.
Does anyone have any idea what could be causing this? I get the feeling I am
overlooking something very trivial.
Thanks,
Craig Holmes
