[FW-1] FW-1 NAT: 3rd Interface

Title: FW-1 NAT: 3rd Interface

Hello,

Currently we have 2 Interfaces in our FW-1 (NT4.0, Ver. 4.1 SP6). I want to put a third Interface into the Firewall, to connect a settlement in another country. The third interface is connected to a router, which knows the routes to the destination (Class C Net 192.168.100.0/24 especially SERVER 192.168.100.2). Rules must be  defined for the traffic over the NEW INTERFACE.

Overview:

                          (OFFICAL IP)
  Intranet --------------------------   FW-1 ------- Router --- Internet
   (NAT 172.25.101.0/24)                I      
                                I              
                        NEW INTERFACE -------------- Router --------------------- COMPANY ------------------- SERVER
                        (172.25.104.2/30)       (172.25.104.3/30)       (192.168.100.0/24)                 (192.168.100.2)

My questions:
1. How is the routing table look like?
2. What do i have to change in the Security Policy?
3. What do i have to change in the address translation table?

Thank you for your help.
