What is the easiest way to implement NAT on a Windows XP gateway,
while avoiding ICS/automatic DHCP altogether ?

Thanks.
 
Flekso,

Without using a 3rd part piece of software, the only way you can implement
NAT is to use ICS on XP. However, if you want to use a different address for
your internal network card, you can do so by changing it from 192.168.0.1
once you enable ICS on your external interface. Changing the IP address of
the internal interface from 192.168.0.1 will also cause the DHCP server to
stop in ICS.

Might I also suggest that if you are using XP as an Internet gateway that
you install XP SP2, if not to use the firewall (if using a 3rd party
firewall), but to keep the system up to date security patches etc.

In the meantime i've found a post that mentions the undocumented
option of adding NAT to protocol stack using 'netsh'...

netsh routing ip nat install
netsh routing ip nat add interface "external" full
netsh routing ip nat add interface "internal" private

....but now i have another problem, mainly because my internet
connection is based on dial-up PPPoE aDSL, so i have two icons in
network connections, one that represents a WAN miniport(this one i
click to connect), and the other that represents NIC that connects to
my aDSL modem.
The problem is my WAN miniport(PPPoE) gets assigned with the external
IP, and the NIC gets an automatic private address(whatever that means)
in the 169.254 range, but NAT won't accept the PPPoE as an interface,
so...

Any clues ?
