ENDIAN Firewall - Connect two networks

Hello,

On this moment I have two routers with two LANs.:
First network:

Code:

WAN (77.79.240.105/28)
     |
    EFW
     |
    GREEN (LAN1 192.168.1.1/24) +--- Server1 (192.168.1.2)

Second network:

Code:

WAN (77.79.240.98/28)
     |
    ZyWall --- DMZ (10.6.3.1/24) --- ServerDMZ2 (10.6.3.199)
     |
    LAN2 (10.6.1.1/24) +--- Computer2 (10.6.1.3)

What I need in final:

Code:

WAN (77.79.240.98/28)
     |
    EFW --- DMZ (10.6.3.1/24) --- ServerDMZ2 (10.6.3.199)
     |
    GREEN 
     + LAN1 192.168.1.1/24) +--- Server1 (192.168.1.2)    
     + LAN2 (10.6.1.1/24) +--- Computer2 (10.6.1.3)

I need have access between LAN1 and LAN2 (in both lans are DHCP servers). I need communicate from LAN1 and LAN2 to DMZ, and from ServerDMZ2 to Server1 and to Computer2.

How I can do it. I have 5 NICs (1 used for GREEN, 2 for RED, and 2 are free).
