Configure bridge in green zone

Hello

appliance Community version 3.2.4
one issue

I've a network with 2 different routers:
First  is a internet router, controlled by RED zone, main uplink is configured with this in order to
second  is a “office to customer  office” fiber line , with another switch with another network class

till now each workstation has a specific routing table with 2 different ip address, one for internal network one to communicate with second router.

problem is  when a WS with DHCP (endian is the DHCP server) tries to contact the second router.
I inserted 2 ip address to the eth0 (green zone) one with internal class and one with second router class

Moreover I add 2 routing table on EFW:
Destination Ip  2nd router/32-->route  by second green zone address
Destination customer server/32--> route by 2nd router

Endian is able to communicate with customer server, so routing is workig  but no one work station s is able to do it, llike endian is not able to address correct ip with his routing table

Any help?

thanks
