In some special case, you may have a public IP subnet from your ISP such as
220.135.240.0/24. This means that you can set up a public subnet or call second subnet that
each host is equipped with a public IP address. As a part of the public subnet, the Vigor router
will serve for IP routing to help hosts in the public subnet to communicate with other public
hosts or servers outside. Therefore, the router should be set as the gateway for public hosts.
