10.5 UPnP Port Mapping Screen
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.
