Hi,
I set up a Firewall for our official Network and use a RFC1918 conform
transfer network to communicate to the router.
Here are my interfaces:
fxp0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500
inet 192.168.55.74 netmask 0xfffffffc broadcast 192.168.55.75
fxp1: flags=8943<UP,BROADCAST,RUNNING,PROMISC,SIMPLEX,MULTICAST> mtu 1500
inet 195.226.65.125 netmask 0xffffffc0 broadcast 195.226.65.127
vr0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500
inet 10.0.0.126 netmask 0xffffff00 broadcast 10.0.0.255
My routing table:

Everything works fine from my official network to the outside and from the
outside to my onet, except the firewall itself.She uses the ip
192.168.55.74 to communicate to the outside.
Is there any way to tell her that she have to use her oip 195.226.65.125
from fxp1?
greetings
