Appendix A: Router Configuration
If you have signed up a consumer grade broadband service, and you use a router to share your internet access, you will need to address following three major issues:
a.DDNS service
b.Port forwarding
c.Demilitarized Zone
If you are not familiar with those network terms, then you will probably need a network technician to help to setup the iGuard.
The following information assumes you have basic knowledge about networking and is for your reference only. Technical support for remote monitoring is only available to those who subscribe to the DDNS service provided by Web Surveillance, LLC
a.DDNS:
In order to access the iGuard from internet, you will have to know the external IP address of your iGuard. If you have a consumer grade broadband service, this IP address may change over time, making it impossible for the remote PC to communicate with your iGuard, just like you ask people to call you but you change your phone number without notified the other party. The solution is to subscribe to a DDNS service which keeps track of your IP address. iGuard is compatible with the DDNS service offered by Web Surveillance, LLC (www.websurveillance.com).
b.Port Forwarding
If you place the iGuard behind a router, you need to programme the router so that it can direct the specific incoming traffic to iGuard.
By default iGuard uses Port 80 for HTTP traffic (web manager) and port 9001 for video streaming. So you need forward port 80 traffic to the internal IP address of the iGuard.
If your Internet service Provider blocks port 80/9001 or you already host a website on the same network, you’ll need to reconfigure your iGuard and router to other ports such as 81/9002, 82/9003, etc.
Note: The section you need to look for in the router is Port Forwarding or Virtual Server
C.Demilitarized Zone (DMZ)
iGuard uses port 9001 by default to stream video to the internet. Unfortunately this port is normally disabled or blocked by most commercial router’s
Some router has a very sophisticated
