Using Dynamic DNS (dyndns.org) with Cisco ASA5500

Hello, has anyone figured out how to implement Dynamic DNS on a Cisco ASA5500? I had it working on my 871W router and have replaced it with an ASA for advanced SSL VPN functions but does not appear to fully support Dynamic DNS updates. Any help would be great!!

Ran into this before...ended up using the dyndns updater utility running on a host machine on the inside network.

Thanks guys, appreciate the info. Still going to try and play with the DDNS as I do see the ASA trying to reach out to DynDns.org however it keeps getting "Refused" messages in the "debug ddns" output. Odd, the provider does not see any of it. The gotcha is that you have to put this big long HTML string into the device that includes username, password, etc..
