Trafton, the serverlist has _nothing_ to do with whether people can ping you or not.

The problem is either a firewall or a bad ISP. Make sure that your firewall is closed (not just off) and that you have no others running. Also confirm that you are not behind any kind of network. Check your IP address (Start->Run, "ipconfig" in 2000\XP, "winipcfg" in 9x\Me) and make sure it doesn't start with "192.168".

Also, what is your operating system? Windows 2000\XP\ have a built in firewall, and there could be a chance that it is on.

If you are absolutely positive that no firewall is blocking it, your ISP could be blocking it. Do other online games work? You might need to contact them and ask if they have any information. If they block games and there is nothing you can do about it, you might have to switch to a different ISP.
