Restrict avahi to listen on specified address

TrueNAS General

It looks like avahi is bound to all IP addresses. How could I restrict it to only bind to the management IP and not any other aliases?

netstat -lnp | grep 5353
udp 0 0 0.0.0.0:5353 0.0.0.0:* 5571/avahi-daemon:

A google search seems to indicate this was possible in an earlier version of Scale.

In TrueNAS Scale, you can limit Avahi (a network service for zero-configuration networking) to a specific IP address by configuring the “Listen Address” setting within the Avahi service settings to the desired IP address, effectively restricting Avahi broadcasts to only originate from that particular IP on the system.

No it wasn’t. That’s probably just AI-generated garbage result. We generally bind avahi to all interfaces with certain exceptions. Services get announced on interfaces that they are bound to. This has been the case since TrueNAS / FreeNAS 9.
