I just installed a LInkssys wireless router for a home network and internet sharing. Set it all up and everything has been going well. My son and I were trying to play NOLF2 multiplayer and couldn't get it started. I remember seeing a section in the router setup for allowing gaming on certain ports and NOLF2 was trying to use port 27888. Well I was going to setup the router to allow gaming on port 27888 but I changed the router user name from admin and have no idea what I used. What can I do about this?
