ok, i can connect to every one of my friends except one. in mw2 both of us cant connect with eachother on any game or party, but when theres another person in the party we can play no problem. im lost, we both have nat enabled. my network is my xbox hardwired to my cisco swich, and that one connects to another swich and than goes into our router, my friends network is his xbox wirless to the wirless router. any idea's here?
