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 Zyxel Device 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 Zyxel Device 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.
