Title: Issues with mDNS Repeater
Post by: jpfeifer14 on June 30, 2023, 08:03:43 am
Has anyone else run into issues with the mDNS Repeater plugin? Initially it worked fine for me, though now I see maybe 3-4 cast devices and the rest do not appear. Interestingly enough, the ones that do appear all chromecast videos, the rest of the devices that do not appear are google home and mini, as well as a google chromecast audio. I have tried several configurations on my managed switch for IGMP snooping, though Im not really sure what all of the settings mean. It seems odd that it worked with the default IGMP settings, and then stopped.

Was never able to resolve this, switched to pfsense with Avahi and it works fine.

UDP broadcast Relay plugin

Broadcast Address: 224.0.0.251
Source Address: 1.1.1.1
Instance ID: 1
Relay Port: 5353

This is for Apple devices, you can google the correct settings for google but should be similar

on my OPNsense 23.7.10_1-amd64 i run into issue with the mDNS Repeater.

is there a know issue with 23.7.10? it was running before, i can't say when it was stoped to work, airprint is not used very often.
one interface is a vlan interface the other interface is a physical interface

i used also the udp broadcast relay but it is the same behavior

when i do an tcpdump on both interfaces i see on the incoming interface the request, on the outgoing interface i see the outgoing broadcast message and alle three printer are answering, but this answers i didn't see on the initial interface.

I didn't see any firewall logs, as well but this could be that i am seared wrong.

Is there any FW rule what have to be in place?

I put some entries on it, but didn't get any success.

any ideas
thx

I'm facing these issues too. Now switched to the mDNS repeater on my Unifi UDM that's in the same network but doesn't function as a router.

now i use a ubuntu 22.04.4 machine with have a leg in both networks and i use "udp-broadcast-relay-redux-master"
i have first to stop the avahi-daemon wtih "sudo systemctl stop avahi-daemon.socket"
and then i start the udp-broadcast-relay with "sudo ./udp-broadcast-relay-redux --id 1 --port 5353 --dev vlan.1 --dev vlan.90 --multicast 224.0.0.251 -s 1.1.1.1 -d"
