     route.conf - static routes config file

     The route.conf file is read by the staticroute rc.d script during system
     start-up and shutdown, and is intended for adding and removing static

     Lines starting with a hash (`#') are comments and ignored.  Lines
     starting with a plus sign (`+') are run during start-up, while lines
     starting with a minus sign (`-') are run during system shutdown.  If a
     line starts with a `!', the rest of the line will get evaluated as a
     shell script fragment.  All other lines are passed to route(8).  During
     start-up, they are passed behind a "route add -" command and during
     shutdown behind a "route delete -" command.

     In this example, the interface for the desired routing changes is set,
     the IP address on that interface is determined, and a route is added
     during startup, or deleted during system shutdown.

           # Set interface and determine current IP address for added route.
           !ipaddr=$(/sbin/ifconfig ${ifname} | awk '$1 == "inet" {print $2}')
           net 10.10.1 -interface ${ipaddr}

     In this example, IP forwarding is turned on during start-up, and a static
     route added for  During system shutdown, the route is
     removed and IP forwarding turned off.

           # Turn on/off IP forwarding.
