My Gentoo router will not port forward.

[oiper]

Hey all, I'm at sanity's edge with this. I've got a gentoo router that I've set up with firehol. I tested my set up a week ago on a different machine to ensure a smooth setup and sure enough, the test machine worked perfectly, but the "production" machine (that needed to be working this morning) is refusing to cooperate.

I'm running 2.6.7-gentoo-r6, dnsmasq, firehol, plus my server stuff. My firewall is performing as it should in regards to my server, but for the love of linux it won't port forward a thing. Help?

The only differences that I can think of between my working test box and the real one, is that:
1. I didn't originally set up the main box
2. It's on 2.6.7 while the test box is on 2.6.10
3. There is an evil gnome hiding behind this desk.
4. 5 hours of trying to do something that should be, and up until now has been, so easy, that I've lost my mind and can't see the problem for all my frustrations.

I'm open to any and all crazy ideas.

eth0 = local - 10.0.0.*
eth1 = inet

My humble firehol config:

Hello

Just taking a wild stab... check your /etc/sysctl.conf. Make sure this is set:

thanks hanj, I could have sworn I'd set that before, but I went back over everthing and got it running.
