Hi,

I've create a private Server for me and my friends.

I think i opend all ports.

Only me and an friend (bought the game) can join, the others cant.

They see the server in the list but can't join.

 

Hope u can help me

 

Server: HLDS-Update-Tool (http://store.steampowered.com/)

Are you sure that the port are open may test it here:

And whats your internet provider?

You should forward the ports if the server is behind the router.
