<![CDATA[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.

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

vs

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

Is there anything functionally different?
