Don't know them off the top of my head, but Google them it will be the first result.
What about placing the xbox in the DMZ? Would I need port forwarding too? Also what is the lowest MTU I can set for my router for Xbox?
MTU is different for most connections you would have to test it to find the best. And I wouldnt recommend DMZ.
Why not DMZ? I wouldn't do it for my PC but it is just the Xbox.
