    I own a WRT54GS and I have the DDNS set to update my account on dyndns.org. Recently however, my dyndns.org account exceeded 30 days without being updated, so the account was terminated.

    This wasn't a big deal since it only take s a few moments to setup the account on dyndns.org. But it does beg the question; how often does the DDNS feature on the WRT54GS update dyndns.org? Obviously it didn't update my acccount w/i 30 days even though the settings were correct.

    Anyone have any idea on this issue? Does it need some kind of "keep alive" switch? Am I missing something?

    Thanks in advance.

    Has your Internet IP changed during the 30 days period? If not, that might explain why it wasn't being updated.

    From what other users have been reporting, the function appears to be quite erratic. One user reported here that his was is being update at regular intervals, which also violated DynDNS rules.

    I use a client application (listed on DynDNS.org) on an always-on computer to monitor changes in my Internet IP, which then updates my DynDNS account for me. On occasions where the IP hasn't changed for long periods (my ADSL connection doesn't change IP unless I disconnect), the application also has the option to force an update. The application generates a log file so I can keep an eye on all its activities, which is better than what the router firmware can do.

    Thank you. Like you I was doing the same thing; using a dyndns client to update the account whether the IP changed or not every 30 days. After getting the WRT54GS and seeing the DDNS option, I figured that it was no longer necessary.

    Your comments would indicate otherwise.

    Oh well, so much for that feature. Back to the client I go. Thanks again for the response.
