Port forwarding
Most computers connected to a router 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. Each port
forwarding rule automatically maps and forwards an external request for a port on a WAN to an IP
address and port on an internal LAN.
For a port forwarding rule to be applied, you must configure From Port and To IP Address, and set
the rule to Enabled. Incomplete and incorrect port forwarding rules are not applied. You can configure
a maximum of 30 port forwarding rules.
