DHCP Relay Not working

Can anyone point out if I'm doing something wrong here?

I have an edgerouter 5 port connected to an edgerouter pro on port eth1 and connecting clients to the switch0 interface.

Edgeroute Port 5:

 interfaces {
     ethernet eth0 {
         duplex auto
         poe {
             output off
         }

     }
     ethernet eth1 {
         address 192.168.123.2/24
         duplex auto
         poe {
             output off
         }
         speed auto
     }
     ethernet eth2 {
         duplex auto
         poe {
             output off
         }
         speed auto
     }
     ethernet eth3 {

         poe {
             output off
         }
         speed auto
