 Hi,

 I am trying to set up gateway using FreeBSD.
 I aleady enable Gateway_enable to yes
 and set sysctl -w net.inet.ip.fastforwaring=1

 I am trying to do this with two real ips
 (both on same network) since my network uses
  only real ips.

  Here is how my nics are set up in FreeBSD

  % ifconfig -a
fxp0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500
        inet *.*.*.3 netmask 0xffffff80 broadcast *.*.*.127
        ether 00:a0:c9:ca:ac:df
        media: autoselect (10baseT/UTP) status: active
        supported media: autoselect 100baseTX <full-duplex> 100baseTX
10baseT/UTP <full-duplex> 10baseT/UTP
fxp1: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500
        inet *.*.*.4 netmask 0xffffffff broadcast *.*.*.127
        ether 00:90:27:66:da:7a
        media: autoselect (10baseT/UTP) status: active
        supported media: autoselect 100baseTX <full-duplex> 100baseTX
10baseT/UTP <full-duplex> 10baseT/UTP

 First Nic in FreeBSD goes to the  hub that is connected
 to the router and Second Nic in FreeBSD goes to
 the hub that is connecting the network.


Here is the topology of the network.

internet - router - hub - freebsd - hub - network

Any help is appreciated

Thanks in advance.
