9.5 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.
Figure 81
UPnP for FTP Access
In the above example, UPnP creates a firewall rule and NAT port forwarding mapping to send FTP
traffic (using TCP port number 21) from the public IP address a.b.c.d to the NAS’s private IP
address of 192.168.1.20.
Use the NAS’s UPnP Port Mapping screen to configure the UPnP settings your Internet gateway
uses to allow access from the WAN (Internet) to services you select on the NAS. You can also set
which port Internet users need to use in order to access a specific service on the NAS.
Note: To use UPnP port mapping, your Internet gateway must have UPnP enabled.

Configuration Port

Network Diagnostic
Tool
Use this section to test the network connection to a particular IP address or domain
name. Select an address or type it into the field. Then click Ping to have the NAS send
a packet to test the network connection.
•
Successfully pinged host - The NAS is able to “ping” the host, the network
connection is OK.
•
Unable to ping host - The NAS is able to “ping” the selected host.
Apply
Click this to save your TCP/IP configurations. After you click Apply, the NAS restarts.
Wait until you see the Login screen or until the NAS fully boots and then use the NAS
Starter Utility to rediscover it.
Reset
Click this to restore your previously saved settings.
