Click ADVANCED > NAT > Port Forwarding to open the Port Forwarding screen. Not all
fields are available on all models.
Note: If you do not assign a Default Server IP address, the ZyWALL discards all
packets received for ports that are not specified here or in the remote
management setup.
Refer to Figure 125 on page 405 for port numbers commonly used for particular services.
Note: The last port forwarding rule is reserved for Roadrunner services. The rule is
activated only when you set the WAN Encapsulation to Ethernet and the
Service Type to something other than Standard.
