NETWORK GUIDE

IF YOU CANNOT CONNECT

If the remote viewing does NOT connect it could be due to one of the following issues:
• Make sure the browser is Internet Explorer 6.0 or higher and is on a Windows PC
• Make sure you forwarded both port 80 AND 9000 for TCP and UDP
• Make sure you properly installed of the controls (selected the yellow pop-up bar and ran all controls)
• Check all your network connections and go through the above steps again to make sure a configuration
error was not made. You may have to configure PPPoE settings to match the settings provided to you by your
Internet Service Provider (ISP). Consult your ISP for more information on your PPPoE settings
• Port forwarding is not set up correctly. Re-review the instructions on www.defender-usa.com/network and/
or www.portforward.com to check if you set port forwarding up correctly
• A pop-up blocker is preventing the ActiveX controls from prompting you to install
• Your router is blocking your computer from using the external IP address from the same network as the DVR.
Try connecting to the External IP Address from a computer that is not connected to the same network
• Port 80 is being blocked by your ISP (Internet Service Provider). Try changing the HTTP port to 2000. Port
forwarding will need to be setup for the new port
• A DSL modem is preventing the connection because it is on a different sub-network. Contact your Internet
service provider to assist with bridging the modem and router together
Error / Page cannot be displayed
Note: If you are having any problems with port forwarding, you can always contact DEFENDER'S 24/7
technical support.
Note: DEFENDER technical support cannot troubleshoot modems, since changing these settings can
potentially render your modem inoperable. Bridging or any other modifications to the modem
will need to be completed by the Internet service provider.
