Your config looks good..
If your 4300 has re filter you have to allow dhcp that traffic or it gets dropped.
set firewall family inet filter RE term allow-any-from-dhcp from source-address 192.168.3.1/32
set firewall family inet filter RE term allow-any-from-dhcp then count allow-any-from-dhcp
set firewall family inet filter RE term allow-any-from-dhcp then syslog
set firewall family inet filter RE term allow-any-from-dhcp then accept
set firewall family inet filter RE term allow-any-to-dhcp from destination-address 192.168.3.1/32
set firewall family inet filter RE term allow-any-to-dhcp then count allow-any-to-dhcp-count
set firewall family inet filter RE term allow-any-to-dhcp then syslog
set firewall family inet filter RE term allow-any-to-dhcp then accept

Client pc is in VLAN 10 and MGMT for dhcp server is VLAN3 192.168.3.1. EX4300 is confiigure as dhcp relay and ex 2300 configure as local dhcp server. A pc direct connect to ex2300 local dhcp server able to grab IP adress but unable to grab any IP if connect to ex4300 go tru dhcp relay.
