Replace gateway with the IP address of the default gateway.
For example, to set the default gateway to 192.168.1.1, you can use the following command:
route add default 192.168.1.1
You can also use the -net option to specify the destination network and the -iface option to specify the interface through which the route should be accessed. For example:
route add -net 0.0.0.0 -iface em0 default 192.168.1.1
This will set the default route for all networks (0.0.0.0) through the em0 interface, with a default gateway of 192.168.1.1.
To make the change permanent, you can add the route command to the /etc/rc.conf file. For example:
route_default="default 192.168.1.1"
This will set the default route every time the
