GRE-over-IPSec with one tunnel endpoint address dynamic - possible?

I'd like to set up a GRE-over-IPSec link where one tunnel endpoint is dynamic.

I know that IPSec is possible with one side dynamic (using 0.0.0.0 as the peer address), but I'm less certain about GRE (normally, of course, "tunnel source" and "tunnel destination" are both needed (though "source" may be implicit)).

Is this possible? NHRP looks like it comes close, but not sure it will do the trick.

Often times complex configuration issues are best addressed in an interactive session with one of our trained technical assistance engineers. While other forum users may be able to help, it’s often difficult to do so for this type of issue.

To utilize the resources at our Technical Assistance Center, please visit http://www.cisco.com/tac and to open a case with one of our TAC engineers, visit http://www.cisco.com/tac/caseopen

If anyone else in the forum has some advice, please reply to this thread.

Thank you for posting.
