you shouldn't use 2.4 yet because it's still in beta.
use 2.2 and the ipchains program. if you need
masquerading AND have public servers you will
also need the ipmasqadm program. if, instead, you
need NAT, you will also need the iproute2 package
and policy routing turned on in the kernel.

you will need to read the IPCHAINS-HOWTO, possibly
the IP-Masqerading-HOWTO and possibly the IP Command
Reference that comes with the iproute2 package.
