[Feature Request] Option for overrding presentationUrl in UPNP Device Service XML

[blindfish]

At the moment I'm blocking access to port 9790 on eth1 of the MinimServer container, to prevent access to the web UI without going through the reverse proxy.
But the presentationURL points exactly to the IP address (and port 9790) of eth1, so all requests for actually serving content are blocked as well. That's my current problem.

By letting presentationURL pointing to the domain name, content is served through the reverse proxy, allowing access control to the web UI or unauthenticated access for serving content, depending on the requested URL.

Edit: Unless I misunderstand what the presentationURL actually does...
