If the DHCP server's interface is not on the vlan in question then something has to forward/relay the UDP requests. In my use cases with Aruba switches I need to configure an IP help-address (separate from the multicast configurations). Works find with both ISC-DHCP and Kea. Unifi must have something similar.
