Cant' join Multiplayer games (IP conflict?)

[nicolasete 10]

Hi there.

Me and my friend have purchased 2 copies of arma 2 and operation arrowhead so we can play online together.

They both work with no problems and we both have joined online servers and played them.

The thing is that we usually play in the same home (so, same internet connection, same router) and when we try to join the same server at the same time the one who joined first gets the "no response for x time" message and the one who connects after him can't join the game.

Is there any way to fix this? we know we can play the same game from the same rotuer (for isntance, we have even got up to 4 players ONLINE (no lan) in a League of Legends match from our router)

And no, we are not using the same cd keys, we have 2 distinct arma 2 keys and 2 distinct OA keys.

Thank you in advance.

Ok, fixed it.

Had a Zyxel P66hw-d1 router with an old firmware wich wasn't allowing us both to join games.

Changed the firmware to the newer version V3.40(AHF.0)b16 and now it works flawlesly.

Cheers.
