I have googled this for a while now but am not able to find answer to this question. I have my xbox bridged to my ubuntu pc. Everything works, maybe just gives an nat error now and then. I want to be able to system link or share files from my computer. My setup is a wireless dongle conected to the ubuntu pc sharing the connecting through network-manager. My routers ip adress is set up as 192.168.1.1 with a subnet of 255.255.255.0.
