What is a valid Dynamic DNS address for 'My identifier'

Hi,
i tried to set my Dynamic DNS to "domain.ath.cx", as my identifier but get an error message: "A valid Dynamic DNS address for 'My identifier' must be specified."
So, what is a valid Dynamic DNS address?

I am trying to setup an IPsec tunnel beetween two sites with dynamic addresses, though i am not sure that this will actually work. But according to Scott Ullrich in this message: "http://www.mail-archive.com/support@pfsense.com/msg03192.html" it should be possible.

Do anyone know if i am suppose to use site2's dynamic address in the "Remote gateway" field? I have tried and pfSense does not complain about the input being letters and not an ip address.

Thanks for a superb fw.

I just found a Dynamic Dns lookup bug. Will be included in beta2.

What's the big difference in using ddns versus using the dynamic domain as a domain name identifyer?

Example: My Identifyer - Domain Name - dyn.dyndns.org

vs

Example My Identifyer - Dynamic DNS - dyn.dyndns.org

Is there anything functionally different?

Different code paths are used to discover the IP. Down the road we will have a helper of some sorts that monitors for an ip change and will let the tunnel failover to the new ip more gracefully.

Ah, that makes sense… and actually that sounds pretty excellent :)
