Nighthawk r6700 Blocking access to various online games

I got this router relatively recently and before I did I had no issues connecting to Halo on my PC, but after getting it I can't get into a game. Xbox networking says Teredo is unable to qualify my NAT type and server connectivity is blocked. A little while later I try Battlefront 2 and again I can't get into games on both PC and console so I try to portforward on console and no matter how I list out each entry nothing works. Is there anything I can do settings wise to turn off whatever my router is doing?
