Thanks for the replies guys,
Ok, so here's my current IP config. Dynamically assigned so i've left the DNS settings and all other values unspecified.
[Network]
SetupNetwork = Yes
StaticIP = No
Ip = 192.168.0.3
Subnetmask = 255.255.255.0
Defaultgateway = 192.168.0.1
DNS1 = 0.0.0.0
DNS2 = 0.0.0.0
In my network, I have a router (10.0.0.1) that's acting as DHCP server connected to a wireless bridge that provides wireless funcitonality. I think that the wireless bridge is 10.0.0.20
Would I be right in thinking that I should set up a static ip address for my xbox, say 10.0.0.3, and DNS1 would be my router, DefaultGateway would be my wireless bridge?
Thanks again for your help!
