Hey guys!
I have been making a dedicated server, and it is all working. When I load up haloceded.exe it works fine. Then when I go into haloce.exe and look for my server, it isn't there.
I asked my friend across the street if he could see it, and he could. But he couldn't connect to it.
I then went back, and could see it. I tried connecting, I couldn't connect. I have forwarded all of my ports, and I still see a maximum of about 20 servers where my friend sees about 400.
What could be causing this problem?

on the screen that show your server list, look to the top left corner and you'll see a padlock symbol.click on that to show password protected servers.and also click on the small square icon beside it, this will show more servers.


also click on the filters option and set them to allow more servers to show up.

To expand on that...

Make sure all those buttons ally told you to click are BLUE. If they are green, then you have disallowed password-protected servers and only allowed dedicated servers to show.

As for the filters, the best way to make more servers pop up is to set "Show Empty Servers" to "Yes", "Show Full Servers" to "Yes", set "Ping" to "All", set "Gametypes" to "All" and set "Show User-Created Maps" to "Yes".

Ok, they are already blue.

Yeah, they are all the same, although I clicked that wierd ring, and it turned blue, and I got all the servers!
thanks you two!
although, back to my original question ... why can't I see my own dedicated server?

If he can't connect to it then you do not have your port forwarding set correctly or the server is reporting the wrong IP number. Find your External IP (http://www.whatismyip.com ) and have your friend try connecting using direct IP. If he can't then your ports are not open or forwarded correctly. If he can then have him check the IP number that is being reported in Game-spy
You won't be able to if the dedicated server is either running on the same PC as your client or your client is also behind the router/firewall.

If the dedicated server is running a a separate PC from your client then it is trying to connect to your external IP address from your internal network and the router will not route traffic that way. You will have to use a direct IP connect to the machine it is running on most likely a 192.168.?.? number.

If you are trying to run both the client and server on the same PC then your are getting port conflict where both the client and server are trying to use the same ports. See:

Everything there is done.
I am running it on a different computer, I've forwarded all of the ports, everything is on ... and my server is STILL not there.

in the init.txt
make sure you have
sv_public true
or sv_public 1
