What is port forwarding? How to set it up in the router?

Port forwarding
Port forwarding is the process that a router or firewall uses to sort the right kind of network data to the 
right port. Computers and routers use ports as a way to organize network data. Different types of data, such as web sites, file downloads, and online games, are each assigned a port number. The router or firewall uses forwarding to send the correct data to the correct place.

A firewall protects a computer by blocking unauthorized information, but if a firewall blocked all the incoming and outgoing data, the computer would be unable to access the Internet. When a computer user wants some data to go through the firewall and to send it to a specific location, he can set up port forwarding. This gives the firewall instructions about which types of data are allowed and how they should be directed.

How to setup

1. Please check the Internal port of the device. (The HTTP Default port is 80)

Go to Network > Network Setup > HTTP Service > HTTP Management Port

 

2. Make sure the Default Gateway IP Address in Network setting as same as Router.

Go to Network > Network Setup > Setup > LAN IPv4 / IPv6 > “Default Gateway IP Address & Primary Domain Name Server”

 

3. Setting up Port Forwarding on the Router Configuration Page (different brands of routers may have different setup page).

  • External Port means the port requested from external connection.

You can set any port number between 1~65535 on the external port on the router configuration page.

  •  Internal Port means the port that will be forwarded to the internal devices.

The internal Port on the Router Configuration Page should be the same as internal devices.

  • To IP address means the private IP address (LAN IP address) of internal devices (NVR or network cameras).
