Did everything by the book but no luck.
I have a newer Netgear router, Comcast ISP.
Static IP on M1XEP, port 2601 forwarded on router.
Selected Obtain DNS auto on M1XEP. FW 2.0.34.
I have rebooted M1XEP.
Can't update clock or FW and test dns fails.
For dynamic DNS, my understanding is that this is only for external internet access but I did use the router dyn dns function.
I don't have anything filled in on the M1EXP Dyn DNS page.
