Linksys SRW224G4 question

Hello,

Thanks for looking. I am trying to get 3 xboxes running on same xbox live connection. I am using a Motorola Surfboard SBG6580 as a bridge with a Linksys SRW224G4 switchboard. I will post my settings for the SBG6580 in a moment as that is the only one I can access. I have no idea what I am doing with the switchboard. I have a Netgear WNR2000 v3 wireless router and Windstream 2701HG that can be used in place of the switchboard. Is any of this a possible set up so I can play in the same game lobby with two of my friends on xbox live? Every time we join the match someone gets kicked off. Sometimes it will work for one game then next game we will be stuck in the "Searching for Players.." screen. This is to play Halo 4 btw. Thanks in advance. I will post the modem settings in a minute.
