My server isn't showing in internet section.

Hi, my server runs perfect (you can connect to it using connect command in console) yet it doesn't show up in the internet tab. Is there something I forgot to do? My startup is: C:\srcds\css\srcds.exe -console -game cstrike -maxplayers 16 +fps_max 200 -port 27015 +map de_dust2 -tickrate 67

Any help is appreciated thank you.
