I tried to connect my xbox360 to my pc with a crosswired network cable. The pc sees the xbox and the connection. After a while thousands of packages have been send both ways, so there is a connection. I set up everything like explained on this site. But when I try to connect to the pc from the xbox, I constantly get the error that no IP address could be assigned. I even tried to use static IP addresses in the network connection IP4 settings of the computer, and use those IP addresses on the xbox but still it can not connect to the computer. And if I run network analyzes on the pc (with automatic IP addresses) there is also an error stating that the IP configuration is not good. On the pc even the MAC address of the xbox is recognized, DHCP is working, and there is an IP address assigned to the connection. I also completely disabled the firewall as a possible solution, but still the same error. I have a mobile internet stick on the computer through which I want to get the xbox online.
