AN) which is accessible from outside of our network to the LAN IP of the DVR (192.168.1.103).



Netopia Router users:



Select Configure followed by Advanced and finally IP Maps. IP map table should be empty, click on add and type into IP Map Entry Name text box the name of your DVR connection, in our example I just typed in DVR so I know what this IP map is for. In Internal IP address box type in 192.168.1.103, for external IP address refer to you ISP work sheet and find out what is your IP. In some cases ISP will provide more than one static IP, you can choose one of them.



Click submit and alert icon located in upper right corner, finally select save and restart.



From now on anyone requesting external IP will be forwarded to the internal IP of the DVR (192.168.1.103), therefore the connection should be established successfully.



Linksys Router users:



When setting up your DVR for access from the Internet, you will need to configure Port Forwarding on your Linksys Router. This can be accomplished in one of two ways, Specific Port Forwarding or the DMZ host. The DMZ host automatically forwards all incoming connection requests to a given IP address on your local network. Open the Applications & Gaming section of the router and choose DMZ. DMZ is not secure and should only be used with embedded, non-PC based CCTV recorders.VoIP technology



To expose the DVR to the Internet, enter the DVR local IP address (192.168.1.103) in the DMZ Host IP address box. In some cases you may just want to forward specific ports to your security DVR. If you are running any other device/server that hosts services available to the internet, you will want to use specific port forwarding instead of the DMZ Host, also if your DVR is PC based it is strongly recommended for security reasons, to only forward ports used by DVR connection. Open the applications & Gaming section of the router and choose Port Range Forwarding. Type in the name for the connection, starting port number, ending port number and internal IP of the DVR (192.168.1.103 in our example). Save and exit.



Your connection is now setup properly.



You probably noticed the term static IP in this article, and are wondering what that is.



Well, static IP is what the name suggests an IP that never changes. While there is no problem with internal IP selection; we can use whatever we want or prefer - the external IP, usually is dynamic. The static IP has to be requested from the ISP and is more expensive than dynamic IP. In our case we do want static IP so we have address for CCTV DVR connection that will never change.
