NetGear DG834PN Help

Hi, I'm hoping some1 here knows Netgear ADSL routers and can help me.

1stly what regarding what I''m going to ask now, yesterday I was still using firmware Version 1.03.30 for my DG834PN and everything worked perfectly.

Then I upgraded to Version 1.03.36. Everything seemed to still work perfectly afterwords, but now I find out there is one little problem...

I have 3 PCs on the network with NAT using
192.168.0.2
192.168.0.3
192.168.0.4
with the router on 192.168.0.1

All the ports are correctly forwarded as it was yesterday (WC3 on ports 6112, 6113 and 6114 on the different pcs) when it ALL did WORK fine.
Now I''m connecting to warcract 3 TFT on our local server. (my pc using port 6112 and forwarded correctly on the router.) I can create a game and ppl can join and we play fine, BUT when any1 of our 3 PCs wants to join the online game another one of the local PCs on our network made it keeps saying "cannot find the game" when we actually see the game and click join on it.
Now all this worked fine yesterday when I had the previous firmware and all the settings is exactly the same now, but it just DONT work since I upgraded to the new firmware.

Help please.
Thx
