routing IP traffic between two NIC's installed in the same server

 

ok, know simple question have mental block , cannot figure out or find answer.

i want run packet sniffer on network traffic.  i want examine traffic before leaves , enters internal network.

i have windows 2003 machine 2 nic ‘s installed life of me cannot think of how route traffic between them , out network firewall.

i want pass traffic network 1 nic fixed internal ip address 192.168.10.x second nic fixed internal ip address 192.168.10.x. within same machine , out gateway. not interested in filtering functions, want gateway firewall retain function interest in examining traffic.

lan > nic  > nic > gateway > internet

how setup routing , remote access accomplish this. 

sorry dense can point me in right direction.  greatful.

   can route traffic 1 subnet another. if both nics in same ip subnet can bridge them cannot route between them.

  want need make internal nic of rras server default gateway lan, set rras route traffic firewall. router-to-firewall segment (like mini dmz) need in own ip subnet (different lan subnet). need route on firewall forward traffic internal subnet rras router (since firewall no longer has interface in segment).  note rras would set lan router only.  eg

        internet
             |
        public ip
         firewall           {static route 192.168.10.0   255.255.255.0   192.168.20.2}
    192.168.20.1
            |
     192.168.20.2     dg   192.168.20.1
           rras
     192.168.10.254   dg     blank
            |
       lan machines
     192.168.10.x        dg      192.168.10.254
