Cisco and DynDns

Discussion in 'Cisco' started by Carsten Schaudel, Oct 30, 2004.

  1. Hello together !

    Today I have a problem with my Soho91 and DynDns.

    I allready got the latest IOS supporting Dyndns. I principly the Cisco tries
    to update the IP there but somhow there seems to be a problem in the format
    of the http-string uses.
    It is exactely in the format described in the cisco sample which also
    matches the instruction on the developer page of .
    Dyndns just doesn't answer. When I try the same http-string in a browser, I
    get the same result - no answer, but only if I put username/passwort upfront
    the URL : http://username:..... Without this it
    works - but I get the 'normal' username / password box then.

    Any ideas where the problem could be ?

  2. Some update here:

    The update-string itseve works - if I use a real browser and not the MS
    interpretation of it, so the string is OK.
    My cisco anyway end up with a timeout when it tries to update dyndns.

    Do you, per chance, have an access-list that is blocking the request? I
    would say to put a sniffer on the outside of the router and watch the
    traffic. Also, try a debug ip packet (or debug an access-list) to see what
    is happening inside the router.

    Hope that helps,
