Avahi mDNS on Wireguard
- 
Hi,
I've managed to successfully access my local network through Wireguard.
Now I'm looking into using the Avahi mDNS repeater which I've already setup on the firewall to repeat over the
172.16.16.0/24subnet which I use for WG peers. Despite selecting thewg0Interface in the Avahi web config (in addition to other VLANs I had previously), and adding224.0.0.251/32to the WG Peer "Allowed IPs" box in pfSense (my client's allowed IPs are0.0.0.0/0), I can't seem to get it working. My clients can't pick up any mDNS devices. I've attached a photo of my pfSense WG Peer config for reference. I've also attached a snipped of my pfTop output for port 5353, looks like my WG subnet (172.16.16.1) is sending mDNS request to224.0.0.251...I also have the "Repeat mdns packets across subnets" option in Avahi enabled too.

@cypherpunk AFAIK, the pfSense Wireguard implementation does not support multicast.
Mentioned in the doc here.
