When I start an offline match and invite my mate he gets an connection error "Server does not respond".
How may I set up a "Offline with Bots" – Server on which my friend can join?
EDIT :
I meant an offline server within a local area network.

There are two methods, you can open up the console in game and type "connect 127.0.0.1:27015" where 127.0.0.1:27015 is your IP address and port number. You have to have the console enabled for this option to work. Usually it's by hitting escape to bring you to the menu and then pressing the tilde (~) key.
Or you can add the server to favourites from in game or out of game through steam. You do this by bringing up the server window, and clicking on the Add A Server button and it will ask you to add the server address to the window and then it will always be there!
You can use http://www.canyouseeme.org/ . Just enter the port, 27015, and the website will try to connect to your server to see if the port is open or blocked by your ISP, forwarded (if you are behind a router) and accepting connections.

You can connect with friends with bots added in all modes except classic competitive simply by going to play with friends and sending them an invite. You can do the same in classic competitive by setting up play with bots game and having your friends connect to your ip address thru the developer console (connect xxx.xx.xxx.xx). You need to port forward to 27015 doing it that way.
