10.5.5.1 Adding a Port Mapping Rule
Some Internet gateways will delete all UPnP mappings after reboot. So if the Internet gateway
reboots, you may need to re-apply the UPnP port mapping again. Click
UPnP Port Mapping > Add
to add NAS services and create port mapping rules.
Select the services you want to create port mapping rules for, and click Apply to add the services.
Click Cancel to close the screen without saving any setting.
WAN Port When you enable one of the NAS’s services, specify the port number (1~65,535) Internet
uses need to use to connect to the Internet gateway’s WAN port in order to access the
service on the NAS. Whoever wants to access a service on the NAS from the Internet must
use this port number.
Make sure there is not another service using TCP protocol with the same port number.
If another device is using the same port (the Internet gateway has the same port number
mapped to another LAN IP address), the NAS overwrites it when you apply the setting and
WAN users can no longer access the other device.
Apply Click Apply to save your changes back to the NAS.
Reset Click Reset to begin configuring this screen afresh.
