packets received for ports that are not specified here or in the remote
management setup.
Click NAT and Port Forwarding to open the Port Forwarding screen.
Refer to Figure 96 for port numbers commonly used for particular services.
Note: The last port forwarding rule is reserved for Roadrunner services. The rule is
