The NAT Server Set is a list of LAN side servers mapped to external ports. We
can configure it in Web Configurator, Advanced Setup, Network -> NAT ->
Port Forwarding. To use the NAT server sets you've configured, a Server
rule must be set up inside the NAT Address Mapping set. Please see NAT
Server Sets for further information on how to apply it.
