A quick post to show how to Enable DHCP Relay on a Distributed Router (dLR). My topology:
Select the dLR, tab Manage > DHCP Relay > Edit
Under IP Addresses insert the IP address of your DHCP server
Under DHCP Relay Agents click the + symbol and specify the interface from which DHCP requests will come from, in my example is the Web LIF.
The gateway IP address is used so that the DHCP server can identify from which subnet the DHCP request is coming from.
My DHCP Server is configured with a Scope for the subnet 172.16.10.0/24
Monitoring my ESG for traffic destined to port 67 (DHCP Server) you can see the DHCP request arriving from 172.16.10.254 and 192.168.1.50 replying back:

And here the lease is visible
