Setting up Remote Viewing - Appendix #3
Network - Router Port Forwarding
You will need to enable port forwarding on your Router to allow for external communications with
your System for ports:
• TCP/IP PORT 6100
• WEB PORT 80
Computers, Systems, 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
216.13.154.34:6100 to System Internal IP 192.168.0.3:6100).
The instructions found online in the Router Configuration Guide will assist you in the port
forwarding configurations for a selection of different router models.

Web - Finding Your External IP Address
You will need to have your External IP address to set up your DDNS account. One of the fastest
ways to find this information is to use a 3rd Party website such as http://www.showmyip.com
Your IP address can also be found within your Router settings. Refer to your router user guide for
further details.
