Bridging mDNS between networks connected via VPN

[janvda]

It looks like smcroute will not route mDNS packets.

see:

• Possible to do mDNS across VLANS without AVAHI, and using smcroute?
  • https://github.com/troglobit/smcroute/issues/99#issuecomment-415953784

So the proposed approach is not viable.
