Using Windows XP as a internet gateway for linux

[cr4sh 0]

Hey im having some trouble getting windows xp to act as a internet gateway for linux ( Fedora Core 4 2.6.11 ).

 

The DNS works fine but when i try to download a webpage or ping a host nothing happens. I have used the command

 

root@BLACK$ route add default gw 192.168.0.1 netmask 255.255.255.0

 

to set up the route tables

 

Can anyone help??
