Appendix A: Network Configuration/Router Programming
a. DDNS:
In order to access the iGuard from internet, you will have to know the external IP
address of your router. 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. As value added service,
iGuard.com hosts a DDNS server that tracks iGuard’s IP address for this very reason
reason. Please logon to
www.iguard.com for more info.
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, exactly in the same fashion how the
telephone switch in your office works.
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, which is quite common for DSL
providers, or you already host a website on the same network, you’ll need to
reconfigure your iGuard and router to use different ports such as 81/9002, 82/9003,
etc.
