I have 4 of your DVRs that I remotely view using a dyndns.org account... all of which works perfectly except when Comcast changes the IP address of my cable modem. Then I have to go to the site and find the new IP, log into dyndns and update. Dyndns says if updates come from a device too often they'll lock them out, so maybe that's why my DVR seems to never update dydns?? On the Network/DDNS setup panel I may have the fields wrong??

Looking for what to look into first. Dyndns is no help: dyn.com/apps/update-client-faqs

Is the device alias the xxx.dyndns.org URL that I connect to, or just the xxx part of that string?

If you have multiple devices in the same IP or Domain , DYN.com will block its updates because every time your ISP changes your IP address instead of DYN receiving one update it receives one from each device. Per location you only need one device to update the IP address, this can be from a DVR , Computer or Router if the routers Firmware allows it.

CoolGreat suggestion Jeff, SRE maybe you can split up the DDNS accounts you can register each DVR/NVR that you've purchased here's the link.

As Jose has mentioned, if all your dvrs are at the same site hooked up to the same router, only one device needs to be the updater. The easiest thing to do in that case is make the router the updater, putting the dyndns account info in it. Then just port forward each dvr's ports within the router and don't worry about setting any of the dvr's up with dyndns- the router handles that. Ideally each dvr should have it's own custom host name to avoid a lockout. But multiple hosts will cost you. Also keep in mind that with a free dyndns account, NO device will update dyndns. You have to go to your host account at dyndns and manually update it. That's the routine they make you do for a free account there. In which case, certainly the techproddns is great. I didn't even know that existed. I use no-ip for free.

One DVR per cable modem, each with a different dyndns address. There is always a router between the DVR and the cable modem, and what ended up working is to have the router update dyndns. When you think about it, DUH: The DVR gets an IP address from the router, not from the cable modem, and that IP never changes. So if the router can't notice the change and update dyndns, nothing can.
