8.5 UPnP Port Mapping Screens
Use UPnP (Universal Plug and Play) port mapping to allow access from the WAN to services you select on
the NAS. It is recommended that you place the NAS behind an Internet gateway firewall device to
protect the NAS from attacks from the Internet. Many such Internet gateways use UPnP to simplify peer-
to-peer network connectivity between devices. UPnP can automatically configure the Internet
gateway’s firewall and Network Address Translation (NAT) to allow access to the NAS from the Internet.
