4.9.1 Port Forwarding > Add Client
Click the Edit icon next to Client List if you cannot see the client in the list. In the pop-up screen,
you can add a new client by entering its Name, IP Address and MAC Address.
A client or device in your network acting as a server for forwarded services (for example, the NAS)
needs to have a static address. If the client selected does not have a static IP address, the IP
address may change when the client reboots, so the ZyWALL/USG may not be able to find it. If this
happens, check for the new IP address of the client. Then add the new IP address by clicking the
Edit icon next to Client List and entering it in the pop-up screen.
4.9.2 Port Forwarding > Add Service
Click the Edit icon next to Service List if you cannot see the service in the list. In the pop-up
screen, click Add, then enter the service name and port range that defines the service. For
example, if you have a FileZilla Server in your network, then enter FileZilla Server as the Service
Name, 14147 as the Starting Port and 14147 as the Ending Port.
4.9.3 Port Forwarding > UPnP
The ZyWALL/USG supports both UPnP (Universal Plug and Play) and NAT-PMP (NAT Port Mapping
Protocol) to permit networking devices to discover each other and connect seamlessly. An enabled-
UPnP or NAT-PMP device can dynamically join a network, obtain an IP address, convey its
capabilities and learn about other devices on the network. If you have a service that requires UPnP
or NAT-PMP, such as a game server, then select Enable UPnP in this screen and click Refresh. All
UPnP-enabled or NAT-PMP-enabled devices may communicate freely with each other without
additional configuration. Do not select Enable UPnP if this is not your intention.
