ok tell me if im doing this wrong. i have two connections, one that is my LAN conection thats connected to the internet. the other one is my xbox connection which has a crossover cable to my xbox. i go to that connection and click the check for "allow other network users to connect through this computers internet connection" and it starts to do stuff then i get this error:

could someone please tell me what im doin wrong. btw there should be a networking forum on here. i think it would be helpful.
EDIT: ok picture wont show up. it was just an error screen saying there is a conflict with the ip address 192.168.0.1
