I'm having the same issue too
My brothe finally got ME3 and for the first time we were going to play a private MP session. (Between 6-10EST Monday night.) I tried to host and it hung on connecting. He tried to host, same thing. After a bit of playing around he found out in some forum that some settings needed to be changed in his verizon router. Ok that done. It connected! YAAAA! after three waves he had to back out so he could get a better mouse. NP. We tried to connect again and again for the next two hours but know luck.
I've never had any problem playing public MP before but I've never tried hosting a privage session. Is there something I should know? I will note that the Galaxy at War was not connecing (all night) but i don't remember that ever being a problem before when i played public.
I have a 10mb pipe so that shouldn't be the problem. I have a I7 and 4gb of memory so that shouldn't be the problem either. My forewall is a TZ-215. I don't think that is the problem since we connected once and I've never had a problem with publice sessions.
This was not a good first inpression for my brother. ANY idea what the problem is? Or is Origin the problem?
Thanks for any and all help you can offer.
