I Have a Belkin router, and I have seen alot of posts on here stating that mp can not be played using them. Well, I am glad to say that with the help of all these posts and a lot of patience, I think I am on the irght road to having it work for me!!!
My router Model number is F5D7230-4, and I live in the Eastern united States with Charter Digital Cable as my ISP.
I went the setup screen online and went the Vitual Servers screen listed under Firewall, on the right of the screen.
In slots 1-8 I have the following port numbers... 2300,2301,2400,2401,28800,29000,47400,47700.
I put them in both the LAN port box and the Public port box, so the same numbers side-by-side. You will need to make sure that you have your own correct LAN IP Adress.
Make sure you have each box clicked 'Enable' and each one will have to be 'set' by hitting the 'set' button.
This game requires the TCP Protocal Type, so do not forget that...
Now, with these settings, I have played a scenario with my JCJS and I have joined a hosted game with my GKCW. My buddy Knupp could not join a game that I hosted, but I will be trying to play with this a little more and keep our community updated on my progress. There is one more port number that I have seen on here that I have not tried to put in so, maybe that is the one I need to host, do not know much about all this either...I will keep everyone posted.
BTW, I do have Hamachi, but do not know much about it, but it almost always enabled and on on my computer, just so that everyone knows.
