If you wish to do this, you will need to build an ssh tunnel from the orbiter to your core. Look at various bits on google on how to do this.
You will need to install openssh on the padOrbiter, because all I have on there is dropbear.
the relevant ports you'll want to pass through are 3450, 3451, and 12000 (for Xine time code).
and the weborbiter will need to be accessible from a static IP inside your 192.168.80.x network.
Basically, you should configure the orbiter inside the network, get the IP address it is assigned, and tunnel that to the remote location.
root password on the padorbiter is 'root'
