Ip Masquerading with FreeBSD

[Guest_imported]

I'm relatively new to freebsd, but I'm trying to set up a gateway from my internal lan to my cable modem. I recompiled my kernel to allow IP filtering and redirection, changed rc.conf to start up natd and ipfw rules that redirect everything to it, but I can't seem to get natd to forward anything out of our internal lan. I have a second network card that is setup with 192.168.5.1, and I want everything from the 192.168.5.* subnet to be redirected out. Nothing I've tried works, and I know I'm really close. I've done this before in Linux, but I wanted to get a little more familiar with freebsd. Is there something simple I'm missing? Or is there a howto that shows some good concrete examples somewhere? Thanks a bunch.

Show me the relevant parts of rc.conf and rc.firewall (of course xxx.xxx.xxx.xxx your external IPs)

Then show me the output of "ifconfig -a", and ps -ax, if possible.

I managed to get it working, my configs were fine but when I recompiled my kernel I had taken out some devices that I didn't have as well, and somehow managed to accidently comment out the bpf device, oops. Thanks anyway.
