Wake on demand (WOD, WOL)

Question

I like to have my homeserver (running Ubuntu) automatically powered on when I am connecting via SSH from the internet.

I successfully configured the server to listen for Wake On LAN (WOL) magic packets on the local network. I can poweroff the server and then send a WOL magic package with wol to start the server. Everything is working :)

But i like to go further: My router (Apple Airport Extreme) is capable of Wake On Demand (WOD). But how can I register my server (e.g. with Avahi) to the router, so that it knows to wake the server when connecting via SSH?

Edit: Some details: If the server is already running, i can connect from the internet via SSH; port forwarding is correctly set up.

You need something to emulate a Bonjour Sleep Proxy client and there is something that does do that: Sleep Proxy Client.

I'd really recommend reading through that page but the instructions for installing it are pretty simple:

sudo add-apt-repository 'deb http://repo.weinlein.info unstable main'
