Install Endian between two networks

[Guest]

Hello,

I need to install Endian 3.0 between two subnets, x.x.40.x and x.x.30.x

I tried putting on red interface the 40.x subnet and on green the 30.x. Port forwarding from red to green allows me to ping, but I cannot ping from green to red, even if in the Outgoing traffic I created a rule.

What do I have to do to permit the connection between those two subnets ? Thank you.

So, my network is like that:

modem
     |
     |                  (----------------------DMZ-------------------------)                  (---------------GREEN---------)                                   
pfSense ------> Proxy ------> webServer --------------------->    Endian    -------------------------> LAN
                                                               <---------------------                  <-------------------------
                                                                        x.x.40.x RED                   GREEN x.x.30.x


The webserver need to access some resources from the lan (GREEN), that's why I wish to connect the two subnets with Endian.
I created a forward rule, which allows me to ping from RED to GREEN, but the second rule, the outgoing rule, has no effect if I ping from GREEN to RED.

I created a RED and GREEN interfaces, because Endian demand a RED interface, I don't know if it is correct, as I actually want to connect two LANs.
Please guide me on how to achieve it. Thank you.
