Network Connectivity Overview

Router Port Forwarding

How do I enable Port Forwarding on my Router?
You will need to enable port forwarding on your Router to allow for external communications with
your DVR for ports:
• TCP/IP PORT 6100
• WEB PORT 80
Computers, DVRs, 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.
NETWORK EXAMPLE

External IP
216.13.154.34
Internet
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
216.13.154.34:6100 to DVR Internal IP 192.168.0.3:6100).
