Separate DHCP servers on LAN and OPT1

[KeyserSöze]

I am attempting to have:
WAN -> DHCP –- Currently working
LAN -> DHCP --- Currently working
OPT1 -> DHCP --- Can't get to work

I am new to pfSense and have followed the online documentation for enabling the interfaces and configuring the DHCP servers.  The WAN DHCP is being provided by the ISP.  LAN is defined by me as x.x.x.1/24 and devices obtain DHCP addresses, both wired and wireless (access points and wireless controller hanging off this interface).  I defined OPT1 as y.y.y.1/24, but devices don't obtain a DHCP lease.  When I statically configure devices with IP in this (y.y.y.0/24) range, they can talk to pfSense box just fine over OPT1 port.

Any help getting DHCP on OPT1 (sg-4860) running is greatly appreciated.  Thanks!

Do you have the DNS address from your interface 10.10.10.1 typed in at the DHCP server page. Picture was too short to tell.

Is dhcp running?

So does your dhcp show discover?  Do a simple sniff on your opt1 interface for port 67 do you see clients trying to get an IP?

UPDATE: Rebooted the appliance and DHCP started working as expected!
