mDNS Repeater not working after multi-WAN

[OPNsense4ever]

I setup multi-WAN recently with the Comcrap LTE modem and mDNS repeater stopped working.

I have 2 interfaces; one trusted and one guest. Trusted has 10.18.1.0/24 and Guest has 172.18.1.0/24 on it. I have a rule to pass traffic from a handful of 172.18.1.0/24 IPs to a handful of 10.18.1.0/24 IPs. ICMP/Telnet/HTTP/etc. all work. I ran mdns-repeater in a screen on the router so I could watch with debug enabled. I see essentially nothing:

Code Select Expand

# /usr/local/bin/mdns-repeater -p /var/run/mdns-repeater.pid -f em0 em2
mdns-repeater: dev em0 addr 10.19.76.1 mask 255.255.255.0 net 10.18.1.0
mdns-repeater: dev em2 addr 172.19.76.1 mask 255.255.255.0 net 172.18.1.0

From both wired and wireless clients I can see mDNS/Bonjour devices without issue given I am on that particular network.

I assume this has something to do with multi-WAN, but I'm at a bit of a loss as to where to start.

Thanks in advance for any ideas.
