DLNA and VoIP over Sophos XG

Good morning together,

Pleas ehave a kind look at the following diagram.

This is how I want to restructure my home network. My concern is, that my DLNA Clients and VoIP Fons will not find their Server anymore. Can you please help me out what needs to be configured on the firewall to pass alls Multicast/DLNA traffic? Do you expect any problems for my VoIP traffic?

Thanks in advance.

DLNA uses uPNP for device discovery, etc. -- and uPNP does not traverse firewalls well, if at all. You may be able to rig something up with multicast routing, which one of my staff tried with his home UTM (it didn't work) ... but I wouldn't bet on it. DLNA specs are just not designed with any sort of enterprise-level security (firewalls, etc.) in mind, typical of the consumer industry.

A little "light reading" regarding uPNP: https://en.wikipedia.org/wiki/Universal_Plug_and_Play

I imagine it won't work with XG either, but you can take a look at PIM-SM routing and see what you can do.
