mDNS/multicast between two UTMs using site-to-site SSL VPN

I recently set up Sophos UTM (9.2 release) on two home built systems between mine and my parents home and have a site-to-site VPN setup between them.  Unicast traffic between them works great, but is it possible to configure multicast traffic between them?  This is definitely not a necessity, but it would be nice to use Airplay audio and video between the two subnets (for the heck of it) if possible.  Any idea on whether this is possible without an external third-party router?

  • If this doesn't just work, you can replace the VPN connection with a RED connection that bridges the two networks.  You'll want a single DHCP server instead of one in each location though.

    If you stay with the SSL VPN, you'll want to change to UDP if you haven't already.

    NOTE 2019-04-26: One reason to stay with the TCP 443 default is that your cellular data provider might block UDP.  My AT&T iPhone XS was unable to establish a working tunnel when using UDP 443 or UDP 1443.  Everything worked perfectly with TCP 443.
