actually I had done that right before we did our Teamviewer session. I actually got it to open back up. I had to once again power down the second XBOX and Power it back up.
While I am glad that worked it will get real old real quick if I have to do that every time we both try to play.
I never had these issues when i was on Charter.
I realize the settings were incorrect the other day when you Teamviewed but that was only because I had been in there messing around and a setting didn't "hold" after rebooting the router. On the other hand I DID turn off uPnP which used to always be on because I swear I read that it needed to be turned off (or I misread that it needed to be turned off
).
I have had this router set up for quite some time and never ran into these problems until we moved and switched ISP's.
