sv_hostport 36963
a = software's randomly generated udp port number at startup b = port number in my server config file c = port number but not same with "a" and "b". d = my real ip (cmyip.com) e = my fake ip (cs2d_dedicated.exe) I start the software "a" creates itself? With my config file i change it to "b"! Some time passes. Software send update request to serverlist with "e" But my ip is "d" and i look to server list (usgn.de/servers.php) i see: "d" + "c" and "e" + some random port number again!!
