Had to change out my Arris Router/modem and lost the port forwarding in the process. Comcast wont let you use the Gateway method any more and forces you to use the "easier" method they provide. Have tried the "easier" method to no avail. Need the port numbers for MW3, The Tech at Comcast help said they are either a two didget or four didget number. I have found 2, 3 4 and five didgit numbers, none of which seem to work.
Can you help me?
