Chapter 10 Control Panel Table 46 Network > UPnP Port Mapping > UPnP Port Mapping (continued) LABEL WAN Port DESCRIPTION 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. Apply Reset 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. Click Apply to save your changes back to the NAS. Click Reset to begin configuring this screen afresh. 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. Cloud Storage User's Guide 118
