Port forwarding rules
Most computers are protected by a firewall that prevents users on a public network from accessing
servers on the private network. To allow a computer on the Internet to connect to a specific server on
a private network, set up one or more port forwarding rules. Port forwarding rules provide mapping
instructions that direct incoming traffic to the proper device on a LAN.
