My srcds server is not accesseble by other players

[JoX]

Hello guys,
i cannot play on my Counterstrike:Source Server when I type in my extern IP and ort .
I use standart port 27015.

I forwarded this ports in my Router:

Code:

css      UDP      1200            192.168.220.118      admin      1200            
css      TCP/UDP      27000      27015      192.168.220.118      admin      27000      27015      
css      TCP/UDP      27030      27039      192.168.220.118      admin      27030      27039

I can play in Lan Modus but not online.
When I start the server this error is given:

Code:

Console initialized.
Game.dll loaded for "Counter-Strike : Source"
maxplayers set to 4
Network: IP 192.168.220.118, mode MP, dedicated Yes, ports 27015 SV / 27005 CL
Executing dedicated server config file
Failed to load Steam Service
Service Start: failed
Connection to Steam servers successful.
VAC secure mode is activated.

So you can see there is no "Adding to Master Server" and the line "Failed to load Steam Service" makes me freak out !!!!!!!!!!!!

Please help me to let my friends play on my server.
