Port 80 is not used in gamefuel rule or priorities. Its a default Internet connection port. Has nothing to do with priorities. When setting up a gamefule rule, depends on how many devices are gaming? I have a buddy that has 3 xboxes, they are set up as 1, 2 and 3 going to port 3074 for XBL. You have to be specific for your ports. Use the port numbers that XBL, PS and other gaming sites and servers use.
