Well, it's already implemented. It's called iproute2 and
can be found with google by the first hit. If you just
want to do 1:n NAT you can stick to ipchains ... -j MASQ and
have fully masquerading. If you intend to implement some-
thing new I challenge you to try implementing real stateful
packetfiltering and NAPT like f.e *BSD or the raptor
firewall has.

You mean kernel core programming?

If you intend kernel hacking, than maybe start with
/usr/src/linux/Documentation/kernel-docs.txt

I haven't bought nor read them all but some of them
are worth reading. The rest is: UTSL!

A good book I recently bought was: "Understanding the
Linux Kernel" from Daniel P. Bovet and Marco Cesati.
It refers to kernel 2.2.x with some additional infos
for the 2.4.x kernels and is dated to January 2001 :)
But you should be familiar with C and basic OS design.
