      I have 5 interfaces defined in pfsense.

      One is WAN. One is a VPN via OpenVPN.
      3 are standard interfaces with their own network cards (LAN, DMZ, DMZ_WEB), and DHCP is enabled on each of these 3 interfaces.

      DHCP is working fine. I have a mix of static mappings and dynamic hosts registering DHCP leases.

      I have DNS Resolver configured to register DHCP leases in DNS.

      Registration is working fine for the LAN interface, but is not working for the other interfaces, regardless whether it is a static or dynamic DHCP lease.

      Is there some setting I am missing on the additional interfaces (DMZ, DMZ_WEB, etc...)?

        @bjk002 - Just for purposes of followup, this turned out to be a firewall / NAT issue. NAT was in place, but one of the associated rules were disabled, not allowing DHCP to occur across interfaces.
