NAT port forwarding allows the ZyWALL/USG to direct incoming traffic from the Internet to the
correct virtual server in your network. For example, if you have a NAS server in your network that
you or other people need access to from outside your network, select the IP address of the NAS
from Client. Then, select the service(s) that your NAS provides (for example FTP, HTTP, HTTPS)
from the Available box and use the right arrow to move each service to the Member box.
Even though the NAS is in your local network receiving the protection of the ZyWALL/USG, you can
still access that NAS using these services from anywhere outside your network.
Run the main Port Forwarding Wizard if you cannot see service you need in the list. In that
wizard you can define other services.
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 Add
here and entering it in the pop-up screen.
