The vendor who professionally installed my security cameras configured my network so I can view my cameras at home remotely from anywhere using DynDns and it worked flawlessly for almost a year. Something happened a few weeks ago where my whole network settings were deleted. I quickly got everything working again except my cameras. I can no longer view them remotely or even within my own LAN. My WAN IP is not within the range of those that are restricted. I can see that it regularly updates the ip address to DynDns but I can't log on to it not through the local ip within my own LAN.
The camera DVR is hooked up to an Apple Airport which in turn is logged on to my Apple Time Machine router that is attached to a DSL modem. Again, this set up worked fine for a year. Before I get the defacto reply to check out the DynDns wizard and the step by step guide, I've already gone through it. They both say that if I can't see my cameras within my own LAN with the local ip, there no sense in following any of the other steps. But what do I do to diagnose or figure out why I can't log on to them? The wan ip keeps updating DynDns. Please help!

There are a number of possibilities, the most likely of which is that your installer left the cameras using DHCP for their LAN IP address. You need to find that address - check the DHCP leases on your DHCP server (probably the router). If you can't find it that way you'll need to
ping all the possible IP addresses on your LAN until you find one that responds that isn't another known device (obviously if the camera doesn't respond to ping requests this won't work).
Start with this guide. When working through that you need to ensure that the DVR has a fixed IP address on the LAN - check the configuration of the DVR (the manual will tell you how to do that) to see if it is set for DHCP or a fixed IP address.

I can log on to my router and see all the individual ip addresses for everything on my LAN. Say I know the ip address for the DVR the cameras are attached to, what do I do then. How do I take that ip address and make it work the way you think my installer did?
Thanks for the help!
