Port Problems

I’m unable to open the ports needed for 2DF and GGPO on my desktop. I have these programs working fine on my laptop with my wireless network but they give me the unopen ports problem on my desktop (can’t host on 2DF, can’t connect in GGPO).

How can I solve this?

turn off windows firewall.
use port forwarding and static ip.

That’s what I thought and a few other people told me this too.

I went to the linksys (WRT150N) setup page, have the ports forwarded there and it only works on my laptop. I have ports forwarded for starcraft also and starcraft works fine, just GGPO and 2DF not working on desktop.

Will do.
