DHCP via Juniper firewall

Hi all,

We are trying to allow DHCP leases from two seperate vlans which are seperated by a Juniper firewall.  Is there any type of ip-helper or equivalent is needed?

How is the networks being separated? I have a similar setup with a sub interface in a different VLAN with it own dhcp server. I use this for business wifi network and guest wifi network at client locations. More details on your setup will help us find you a workable solution

The setup is something like this:

dhcp server [vlan A] >> switch [switch vlan A] >> juniper firewall interface [vlan A] >> << juniper firewall interface [vlan B] << switch [vlan B] << dhcp client [vlan B]

The dhcp server has been configured with a scope  for vlan B, however,  the dhcp client is not recieving IP address from the DHCP server.

thanks
So just to be clear. You have one DHCP server and it sits in VLAN A. It has the scope for VLAN B configured and you would like clients connected to the switch for VLAN B to get up addresses across VLANs?
Yes,   that's correct sangamc.

thanks
