[ijulien]

English: i have allow altitude on the firewall but the server is for other people "unresponsive". I can only play in my network. HELP ME PS: i have a mac, i need help for a mac.

German: ich habe altitude den zugriff auf meinen mac geben, doch wenn ich die maps mit dem serverlauncher hochlade, kann ich sie nur in meinem netzwerk spielen. wiso ist der server für andere unemofänglich? ich hab n mac also brauch ich hilfe für nen mac.

Hope for help soon.

Have you made sure you're opening your ports? You need to make sure all of altitude's ports and all of the server launcher's ports (listed when you start the server) are open to either TCP or UDP, I can't remember which altitude uses but the FAQ on the wiki is pretty detailed.

You need to set up port forwarding on your router to allow incoming connections.

In this case you need to log in to your router and forward the port you chose for your server (e.g. UDP 27276) to your machine's local IP Address. You may find the guides at http://portforward.com to be a useful reference.
