New modem/gateway/router/switch/AP

I've got a new modem/gateway/router/switch/AP and configured it. So the temporary modem from my girlfriend can go back to her place.

The device possibilities are quite extended, although I think the configuration (at least the web configuration) doesn't offer all possibilities I'd like, but nothing I can't live with.

And this time I did check if my server was reachable from the internet...
