If someday under FreeBSD you have a system with multiple IP address on
the same network and you need to use a specific IP for a route, you
have to use the -ifa parameter in the route command.

In our example, we have to use the address **** to access
the network **** through the router ****, this
is as easy as the following.

    route add -net -ifa

You can add this specific route like any other route in your rc.conf
as usual, just add the -ifa X.X.X.X parameter.
