Take a look here:
http://netfilter.samba.org/documentation/
for pointers to lots and lots of detailed explanations. The
answers you want are in there - but you'll need to do some studying.

That's right. You don't need any for your application. Remember
that netfilter rules are generally for **filtering** packets, not
for forwarding packets.
Take a look at the line towards the bottom of the script I sent
that turns on IP forwarding. That line turns your Linux system
into a router. It tells the kernel to forward packets from one
ethernet interface to the other and out to the network on the other
end.
The -t mangle stuff is just being thorough. Netfilter has several
tables and the mangle table is one of them. It's good practice to
flush and zero all tables when you set these scripts up. Take it
out if you want.

Sigh.
I don't see any FORWARD rule here. You know, like between the
interfaces. And what's '-t mangle' got to do with anything?
*Let the fellow go to a list that will look after him properly*
Best,
