Router Port Forwarding

You will need to enable port forwarding on your Router to allow for external communications with

your DVR. Enable port forwarding on:

• Port 14337

• Port 14338

Computers, DVR’s, and other devices inside your network can only communicate directly with

each other within the internal network. Computers and systems outside your network cannot

directly communicate with these devices. When a system on the internal network needs to send

or receive information from a system outside the network (i.e.. from the Internet), the information

is sent to the Router.

When a computer on the Internet needs to send data to your internal network, it sends this data

to the external IP address of the Router. The Router then needs to decide where this data is to

be sent to. This is where setting up Port Forwarding becomes important.

Port Forwarding tells the router which device on the internal network to send the data to. When

you set up port forwarding on your Router, it takes the data from the external IP address:port

number and sends that data to an internal IP address:port number (i.e Router External IP

216.13.154.34:14337 to DVR Internal IP 192.168.0.3:14337).

The instructions found online in the Router Configuration Guide

will assist you in the port

forwarding configurations for a selection of different router models.
