I've never used Mandrake, but if it has a simple option in some dialog,
it probably just hides the real implementation details from you.

To make changes permanent:

1. enter
net.ipv4.ip_forward = 1
in /etc/sysctl.conf

2. make sure you have routing set up correctly

3. make sure you have netfilter (aka iptables) set up correctly with
whatever filtering you need, plus MASQUERADE or SNAT, depending upon
whether you have a dynamic or static shared address

Your spiffy Mandrake option probably did 1 & 3 (at least MASQUERADE) for
you.

Thanks a lot for the input. I will give it a try.
Is there a built-in NAT?

I'm not sure what you intend by "built-in."
The netfilter actions MASQUERADE, DNAT, and SNAT accomplish NAT.
"man iptables" and/or Google zillions of pages for more info.
