I am fighting with this problem more then three weeks. Let me explain. I use a ATT account with a Motorola 2210 modem in bridged mode. Behind this modem I use a WRT54g router. All my ATT account information is correctly in the modem. Stay alive is manual 180, DNS account is setup and in the router. I use fort forwarding to my Avtech security DVD recorder ( port 80 ) In my recorder I have a Static port ( 20 ) all settings are correct. I use the dyndns account into my iPad to login my dvd recorder and watch 8 camera's online. This works perfectly untill ATT changes the public IP address. Then I have no access anymore to the recorder system. If I check via dyndns the public IP address from the stand alone system and then I ping this address, then I get send and receive bits 47Ms. So I know my modem is not down or whatever. If I put this public IP addres in my browser and :80 behind it, also I do not get in the recorder, also no access with :8080 to the router. What is wrong ?? |

It sounds like your hostname isn't updating correctly, which suggests a problem with your update client. What are you using to update your hostname - your WRT54g or your AVTech device? Note that when you check your DynDNS hostname for the IP, all you are getting is the IP it was last updated with. If your IP has changed and the client is broken (or you haven't configured one) then you will be seeing the previous IP still. You may want to work through this sticky.
If your AVTech doesn't have a functional update client you may want to replace the router with one known to work, or replace the firmware with DD-WRT.
Once you've configured it then it will send an update. If you don't manually update it then it is, to some degree, working. Unfortunately you won't know if it's correctly working until the WAN IP changes.
That depends on the ISP. |
As the problem is apparently with the built-in DDNS update client of the router, you would disable this and use the DVR's update client instead to see if this is more reliable. Nothing can be done remotely yet as long as you don't know the actual IP address. |

I use the WRT54g to update the hostname. There are no other computers on the network. It is only the Motorola 2210 modem, the WRT54g router and the Avtech 8 channel 264 recorder. I could use also the AVtech to update the hostname, but I decided to do it in the WRT54g because this one is direct behind the modem. At this moment I cannot access anything, I only ping the latest known Public IP address, but this could have been changed, maybe I ping a address from a other Public user at this moment, I have no idea. The stand alone system is on a remote location, for security reasons no person has access to modem, router and recorder. I need to make a 3 hour flight to go to this location. How can I make this a stable platform. Thanks for the information, tomorrow someone is flying to the remote location. Will do first a reset of modem and router ( 12 Volt off and on ). Then try if he can localy access the router and try a webbrouser page like google or whatever. If this work, then I have remotely access to the settings of the router and will remove the DDNS account in the router and add the DNNS settings in the AVtech recorder. How can I test if after a renewal from the Public address update client is working. Will removing the 12Volt on the modem give me a new Public address ?
