Yes. Recompile with ipautofw and all the IP Masq stuff.

Do the rest of the kernel settings for your system (kernel-howto).
Make sure you;
make modules
make modules_install
After you have done;
make zImage
Add this to /etc/rc.d/rc.local
ipfwadm -F -a deny
ipfwadm -F -a m -S 192.168.0.0/24 -D 0.0.0.0/0
insmod ip_masq_ftp ports=21,20,69
insmod ip_masq_irc ports=6666,6667,6669,6668,7000
Do make sure you read the ip masq mini howto.

Once you have recompiled and installed this kernel ipv4 forwarding will be
on. You won't need to turn it on anymore.
