      I have a dual WAN failover set-up. Its working fine, but when the gateway group fails over to the tier 2 gateway the Dynamic DNS service is not updating the IP address to the failover WAN. I'm trying to update DNSOmatic.

      During fail-over, Checkip.DynDNS.org is reporting the correct IP for the failover WAN. In Services > Dynamic DNS Clients, the cached IP is shown as primary WAN IP (vs the fail-over WAN IP) but in Red text.

      Any suggestions as to how to get the fail-over WAN IP to report to my Dynamic DNS service?

          Hi,
          thats, because the dyndns update service is just triggered once a day at 3am from a cronjob.
          Follow this steps, to fix your problem:

          1. Install the Cron package
          2. Go to Service --> Cron
          3. Change the hour and the minute from the "/usr/bin/nice -n20 /etc/rc.dyndns.update" entry, to "" "".
            After this change, the DNYDNS service will check your gateway IP address every minute and update it if necessary.
            Sure you can change the values from point 3 to every value you need!
            Regards

              Your DynDNS is configured on the GW Group you are using as "interface to monitor"?

                Yep. I made the changes to Cron suggested by @Crysion but haven't had a chance to test it out yet. Hopefully that resolves it.

                  Unfortunately, changing the cron timing didn't seem to make any difference

                    @Ximulate,
                    on which interface your dyndns is listening? I had to configure the LAN Device, to get it work.

                      Interesting. Thanks. I had it set to the gateway group. Just switched to LAN, but it may be awhile before I can test it again.
