Cannot contact devices on other vlans from LAN with hostname

[mkono87]

I have a VLAN that I have setup for my homelab devices to keep it isolated. I have allowed my desktop from the LAN to access that VLAN. I have no problem with using IP addresses.

LAN - 192.168.10.1
HOMELAB(VLAN 30) - 192.168.30.1

I have the adguard plugin setup on opnsense and unbound using port 5353. In adguard, I have an upstream entry for [/local/]127.0.0.1:5353. When I ping a device with its hostname, I just get host not found.

I feel like its something simple like FW rule or something. I dont have any rules pertaining to dns atm as I didnt seem to need any. In the VLAN interface on Opnsense, the dns server is blank and using the default in settings/general which is the LAN gateway.

Anyone? Im feeling it might be a bug as on each interface, I have the registered static dhcp entry checked but hostnames only resolve on LAN.
