Dyndns failover option ?



  • Why isn't it possible to use an failover interface (1st wan than opt1) for one dyndns account (or one Dynamic DNS client) ?
    Other routers I worked with (professional) had those options.

    Because nobody has had the time/motivation/funding to do that yet :-)

    It's something that has been asked for before, but has yet to be implemented.



  • you could mess with floating rules to redirect stuff with direction out , dest dyndns-update-server, gw=failovergroup

    it'll take some tries but i have seen it work



  • can someone go into a little more detail on what the end goal is?

    i dont think i can help, but i use dyndns and it might be something that is probably very useful.

    thanks.

    tomdlgns,

    The scenario would be, for example, a dyndns entry for something like www.example.com pointing to WAN1. When WAN1 is up, the dyndns host is updated with the IP of WAN1.

    Then WAN1 goes down, when this happens, www.example.com dyndns entry would be updated with the IP of WAN2 instead of WAN1, following the tiers of a gateway group or other similar setting/ordering.

    When WAN1 comes back up, www.example.com dyndns entry goes back to WAN1.

    Effectively it would allow a sort of failover between WANs for inbound connections (for people who can't get their own IP space and BGP…)

    thank you.
