I am having problems correctly networking my two computers.

One runs only Windows XP Home and connects to a broadband internet connection, the other has SuSE 9.2 Pro installed.

I managed to temporarily acces the internet from the linux machine using Samba (the linux computer as the server) but have not been able to since. They both seem to be talking to eachother because the XP machine shows that packets are being sent and recieved.
Thanks.
