mdns-repeater kills network

[Panther5314]

Hi all,

Decided to give 24.7 a go, started from scratch, moved over to the new kea dhcp, setup firewall rules etc. All seems to be working fine until I installed and activated the mdns-repeater plugin.

I have a vlan for mobile devices and one for IoT devices. In my previous config, i had mdns-repeater enabled for both these interfaces which worked perfectly. However, when enabling it on the same two interfaces in 24.7, i get packet loss and can't connect to the web interface.

Unplugging the cable from the IOT interface allows me to get back into the webui to disable the plugin.

Any tips on where to look for root cause?

Figured i'd come back with my tail between my legs and admit that i'm an idiot.

I left my old instance of opnsense running (with all dhcp scopes disabled, different IPs etc) so i could compare my new setup to the old.

Totally slipped my mind to disable the mdns repeater on the old instance - im assuming what lead to an infinite loop of mdns repeating

disabled the mdns repeater on the old setup, no issues!

Hi Panther,

Just letting you know that I'm not running the beacon at all and have the same control/access as if I'm running a dumb/ISP router.

I have 5 vlans where only two are fully trusted. All others can't even get out to WAN.

192.168.140.0/24 ← LAN/mgmt/(trusted)
192.168.141.0/24 ← IoT
192.168.142.0/24 ← neighbours
192.168.143.0/24 ← Guest
192.168.144.0/24 ← IP CAM
192.168.145.0/24 ← Raywood/(trusted)


I have an AppleTV statically assigned to 192.168.141.8 within the IoT vlan, I allow it (only) out to WAN but nothing else on this vlan.
I've also enabled 192.168.140.0/24 and 192.168.145.0/24 access to the AppleTV only and all seems well for controlling homekit devices either at home or when elsewhere.

Cheers.
