Hello, I'm new member.Yesterday, I was host on multiplay mode without open port so when I host, no one come .But now I can host and everybody can see my room. Ya, if you want to do that you have to do these step: 1/ Click start/Run/Cmd type: ipconfig/all . You will see something like this, remember your Ip address. For example: You see that? My ip address is 192.164.1.35 and my default gateway is 192.168.1.1 Next: open your web browser ex: Firefox, IE, Opera... type your default gateway (my default gateway is 192.168.1.1) If your router asks for a username and password, the default setting is no username and the password is admin or 1234 + On Linksys routers its "admin" for both user and password. + On Netgear Routers its "admin" for username and password for password After login, you'll see the router's information page. Like this: Click Network/Nat/Port forwarding/Service name/User define. You'll see this page. For example: My router is zyxel P-600H-t1-v2 Click active,and fill the box: Service name : Emergency 4 (or another name you like) Start port: 80 ( This is default port, you can skip open port 80 because some router has already opened it) End port : 80 Server IP address : your IP you have seen (192.168.1.xx) Then click apply.Ok you have port 80, now you need 2 port: port 58282 and port 12345 Just do it again: Service name : Emergency 4 Start port: 58282 End port : 58282 Server IP address : your IP you have seen (192.168.1.xx) and Service name : Emergency 4 Start port: 12345 End port : 12345 Server IP address : your IP you have seen (192.168.1.xx) Ok click apply.And now you have 3 port. Now you can host the game. If you want to check your port is open. Download this file http://portforward.com/store/PFPortChecker.exe after you install. Just check your port, if the port is opened, it will say "both TCP or UDP is ok!" If you has open those port but your PFPortChecker say it didn't, you should turn off firewall of windows and ones on your antivirus software ( such as: Kapersky, comondo ...) Good luck! From bennie900: I recomend this guide: http://portforward.c...0v6/default.htm It's not the same as your's but its the same layout. Follow the guide for the ports posted in page one. Anyone else who is having problem visit: http://portforward.com Select your router model and make, then it will tell you. You may have to click "Default Guide" on the page since some games are not listed. If everyone have a question please ask here. Sorry for my English Because I'm from Viet Nam
