Intel Mac & GameRanger

Hi - I have a new Intel iMac 2GB and am having a problem with GameRanger and Ghost Recon. I can play the game fine solo but cannot join anothers "server" or host a room and have others "join". I have my firewall off and have disconnected a Vonage router. The game plays fine in solo mode, on and off GR with CD in Mac. Any ideas? Maybe the Intels can't even support multi-player games on GameRanger but I'm sure there are others there who have Intel Macs. Love the game and playing with friends. Help.

Thanks so much.

This sounds like more of a networking issue and less of a Mac issue.
You could also check with your ISP as some do still block ports that can interfere with gaming.

Thanks. I think you're right.

I talked to Comcast tonite and he gave me a list of "blocked numbers" that they use. Where do I put them? How do I use them to gain access to multi-player mode? Thanks
They are 67-68-135-137-138-139-445-512-520-1080
