@OBARRERA as long as the DHCP relay can acces both the subent and DHCP server there sohould be an issue. If the relay cannot access the DHCP server because of the way the network is configured you need to take another approach.

Yep, if your MX is serving a VLAN it can play relay server, so you just configure DHCP as relay towards another IP. You only have to be sure your MX has a route to the subnet where the DHCP server is at and that the DHCP server subnet has a route to the VLAN the MX is gateway of.
