I'd normally post this in misc, but it actually has to do with JJ2.

I have been trying to play JJ2 online with the Alcatel SpeedTouch 510 series modem. This modem is sort of common in The Netherlands. Until now I didn't have any success but I thought someone might have managed to play JJ2 online with it. If you did, could you please contact me? Thanks in advance.

(and yes, ofcourse I tried port forwarding)
