Port Forwarding allows the option to run a publicly accessible server on the home network by specifying the mapping of TCP and/or UDP ports to a local device.  This enables incoming requests on specific port numbers to reach devices such as Web Servers, Mail Servers, Digital Video Recorders (DVR) and gaming devices. Port Forwarding is setup by entering specific port(s).  This document contains the following sections:
Requirements
- Client device IP Address
- The port number(s) and protocol (TCP and/or UDP) of the service
After completing the port forwarding setup, it is recommended to reserve the IP address of the client device that was set up for port forwarding.  Please refer to article 19140 - SURFboard Central: LAN IP Reservation Setup.  Port Forwarding Setup
