How to host Warcraft III games?

[Exid]

I have a Belkin 54g wireless router. I followed all the steps on the website (see quote below).

I highlighted the sections that petain to my situation.

This is because the router is using a NAT firewall and the computers on the router are behind this firewall. You can fix it but only one computer is able to go on the other side of the firewall to play an Internet game or videoconference at a time. To do this you will need to use the DMZ settings in the router set up screen. First you will need to find out the IP address of the computer you want to put in the DMZ. In Win95/98 and ME click on Start and click on Run. Here type "winipcfg" and push Enter. This will bring up the IP configuration screen. In the drop down box choose the network card that you are using with the router. Here it should give you an IP in the 192.168.2.xxx range. Remember or write down that IP address and close the IP config window. In Win2000 and Win XP click Start go to Program and to Accessories. In there choose Command Prompt and type IPCONFIG at the DOS prompt. Remember or write down that IP address and close the IP config window. Now open you Internet browser and put in the router IP address, it should be 192.168.2.1, in the address bar. Log into the router and from the main screen click on Initial setup off to the left. On the next screen choose DMZ. Here you will need to click enable and type in the last digits of the IP address you just recorded earlier into the box there. Click the Enter button at the bottom to save that setting. You should now be able to use videoconferencing and Internet games. Remember to come back into the Router setup screen and disable the DMZ so that your computer can once again be put behind the firewall so it can be protected.

I went to 192.168.2.1 then logged in and clicked on the DMZ link. Then when the screen came it, it said xxx.xxx.xxx.yyy where X is the first part of my ip address which was already entered in by default, and y is a box where I am supposed to enter in the last digits of my ip address. Well I went to command prompt (Im on WinXP) and did ipconfig and entered in the last digits of my Private IP address (NOT Default Gateway or Subnet Mask ip's) and checked the Enable box. But I still cannot host games.

I have all other firewalls disabled on my PC, but for some reason I still cant host games. Any and all tips are appreciated.

Did you set up port forwarding? It's necessary for direct connections for some games if you're behind a router.
Port Forward
Different routers have different methods, and that site lists a great deal of individual models with instructions.
