[SOLVED] mDNS over VLAN works only for DHCP assigned IP addresses

[molnart]

Interesting  issue, but potentially dead simple here:

hostname resolving across and on VLANs is working only partially. hostname of devices where IP address is assigned via DHCP works, but static IP does does not work (nslookup fails)

my firewall rules for the VLAN allow port 53 to OPNsense firewall and 5353 to 224.0.0.251. mDNS repeater plugin is installed and enabled.

what did i miss here?

Edit: as i assumed it was dead simple: had to enable Register DHCP static mappings in Unbound
