Hi Angel,

Unfortunately, the ASA only currently supports DDNS updates using RFC 2136 and does not support the HTTP-based updates that DynDNS uses. However, there is an enhancement request filed for this (CSCsl46782). You can use this link to follow the status of the enhancement:

Enhancement feature for Dynamic DNS using http-based updates:

http://tools.cisco.com/Support/BugToolKit/search/getBugDetails.do?method=fetchBugDetails&bugId=CSCsl46782

Hope that helps.

Hi Guys,

I know its been a few years but has anyone managed to get the ASA 5505 working with one of the free DDNS providers?

Thanks

Haven't tried it yet. I ordered an ASA5505 yesterday and hope to use DynDNS for it. If not, I'll have to place a home router, or an 1841 in front of it to get it to work. I'll update this page if it works or not.
