DNS Resolver - DHCP registration - Multiple Interfaces - not registering in DNS

[bjk002]

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.

not allowing DHCP to occur across interfaces.

What? Sorry but no..
