Hey roi_tkh,


set forwarding-options helpers bootp server 192.168.20.223
set forwarding-options helpers bootp source-address-giaddr

OR

set forwarding-options helpers bootp interface vlan.19 server 192.168.20.223
set forwarding-options helpers bootp interface vlan.19 source-address-giaddr

The "source-address-giaddr" ensures that the dhcp request comes from the layer 3 interface of vlan.19 thereby ensuring that the client gets the correct address assignment from the dhcp server.

Cheers,

Bailey
