Endian Firewall routed subnet on green network

[Guest]

[mx2504t]

I am trying to set up an endian firewall appliance and having a hard time with internal traffic routing.
Here is my setup:

Green subnet: 192.168.200.0/24
Endian firewall IP: 192.168.200.254
Additional internal routed subnet: 172.16.200.0/24
gateway ip address: 192.168.200.254

Either way, devices on 192.168.200.0/24 and 172.16.200.0/24 are unable to communicate properly.  For example, If I can do a simple ping from  192.168.200.x/24 to an ip address on 172.16.200.x/24, not work. If I can do a simple ping from  192.168.200.x/24 to an ip address on 172.16.200.254/24 work.

Internet access from both works fine, it's just communication between the 2 subnets that isn't working. 

When I add the static route through the web based gui, the connections status page shows traffic coming from the 192.168.200.0/24 subnet direction 172.16.200.0/24 as red (internet traffic).
Routing table seems not to work. I have some subnet behind the green interface, I set up a route on the Nework -> Routing form, but no route results in the roouting table.
In fact if I make a traceroute EFW uses the RED interface to try to reach hosts in other "green" subnet. I also tryed to reboot EFW but nothing appens.

Is EFW able to manage subnet behind GREEN interface or not? Can I manage them form the web interface?

Thanks!
