The network UI has gotten pretty good at displaying information about all the network interfaces configured on the host, but there’s no way to tell H-A which interface should be used to advertise mDNS.
It’d be great it that were added to the menus.
Presumably, being able to edit the default network interface would also work as an alternative.
I think I saw it in the network settings and it have been there for some time.
I don’t see it. There’s an option to pick which interfaces to use for discovery, but that doesn’t change which interface is treated as default.
mDNS is discovery
I’m talking about the H-A mDNS advertisement (the local hostname.)
The description on the network section says "Configure which network adapters integrations will use. Currently this setting only affects multicast traffic. A restart is required for these settings to apply. "
The dialog for selecting networks is claims it’s picking which interfaces integrations will use for multicast traffic. It doesn’t necessarily follow (absent documentation) that the DNS advertisements are going out on the same selected interface(s).
In any case, I want integrations to be using multiple interfaces to reach the correct VLAN segments, but I only want mDNS advertisements by H-A to go out on a single interface/ip address.
True, but most features in HA is actually considered integrations still. They are just built into the core.
I would guess the mDNS service bind to that interface in the GUI.
In any case, being unable to specify which interface that service uses causes problems with the mDNS advertisements.
