(adsbygoogle = window.adsbygoogle || []).push({}); a friend of mine called me yesterday with this issue:

- he has 2 PS3 on his house
- he is trying to play MW3 in a party with the 2 consoles.
- everytime he invite the other player, he is not able to enjoy the game.
- I created a game from my house and invited both. As the first player was in the party and the second one enjoyed, the first was instantly kicked out.
- one of the players has NAT-Typ Open the oder strikt.
- i saw his router config on a teamviewer session and it looked OK. Both consoles had diferent IPs, diferent MAC-Adresses. So there wasn't an IP-Conflict.


After reading many stuff on google i decided to change some settings on his rooter:

- i modified the config so IP x.x.x.x would act as a DMZ. This IP i allocated manually on the PS3 from Player 1 (NAT open), then we tried again. It is working now...


well, i still not knowing what exactly is going on there, but i got it working making this DMZ change on his router. Im affraid, that if i put one more PS3 on his networking, this PS3 will have the same problem.

Can someone help me out here?

Thx!

I think your modem/router cant handle that.

me and my neighbour are able to play mw3 in the same party (he uses my internet)

im using virgin media superhub

so it may be a few settings on your router need ajusting

but u can still have 2 ps3's in the same house playing mw3 at the same time

try reseting your router or put 1 ps3 wired and the other wireless

all the traffic must be causing a strict NAT type, youtube it to find more about this problem XD
