i am def gonna have to buy a new router now as he has figured out how to bypass the blocking.
Basically i have the router dhcp enabled with an ip range going up to 6 and had the mac of his xbox configured to a certain ip address.
I have just seen on the router he has put his xbox to a .7 address and he is now able to get online even though i only have an ip range of upto 6 setup.
Any ideas why this would be??
