I have read a few forums and walkthroughs where a lot of people, often everyone, eventually had sucess in connecting their XBox 360 to their mac and accessing Live. I have tried everything I can find to make this work. Here is what I have done: I am running Leopard and using a Linksys Router. I began with the following: On the iMac: Ethernet Connection (manual) IP: 10.0.0.1 Subnet: 255.255.255.0 Airport IP:192.168.1.100 On XBox: IP: 10.0.0.2 Subnet: 255.255.255.0 Gateway: 10.0.0.1 Primary DNS: 192.168.1.1 Secondary DNS: My Routers WAN IP (found on whatsmyip.org) Next, I tried changing the settings to the following On XBox: IP: 10.0.0.2 Subnet: 255.255.255.0 Gateway: 10.0.0.1 Primary DNS: 192.168.1.1 Secondary DNS: 192.168.1.100 Last, I tried using making the primary and secondary DNS addresses the same. Every time I have the same problem.... it fails when testing the DNS........ PLEASE SOMEBODY HELP!!!
