Resolve Hostnames on multiple (V)LANs

[karsten-heck]

I have finally made to setup pfSense the first time, such that there is one physical port delivering three networks - so a trunk port with a default network. I guess the image contains nearly all information

What is missing:
there is a default domain name: home.local and one domain name for each vlan: hypervisors and guests. Those additional domain names are set at the respective DHCP Server for each network.

Now there are two debian hosts having this /etc/network/interfaces config:

So both hosts get three ips one for each network.

In theory - at least in my version of it - I should be able to ping each host by <hostname>.home.local, <hostname>.hypervisors and <hostname>.guests. But no matter what I am trying here, only the first version works.

Specifically I have used these commands:

dig hostname.home.local
dig @10.11.30.1 hostname.hypervisors
dig @10.42.7.1 hostname.guests

Should that work in Theory but doesn't because I have screwed up the firewall rules, or am I trying something that is not expected to work at all?

UPDATE

By searching for similar Topics I ended up in this pretty interesting thread: https://forum.netgate.com/topic/141647/dhcp-not-registering-hostnames-in-dns/10

So I just cat /var/unbound/host_entries.conf while two clients were connected. There I could not find any hint of the domain names set via services > DHCP Server > domainname (respective tab for each interface)

From the absence of any Entries there I subsume that the behavior I am seeking is not provided?
