It looks like the "How To" has already been fixed for me, or more of my ignorance is showing . CanYouSeeMe.org gives me an IP address that pings, should I be able to ping port 21 that I have forwarded?
It's likely that the address shown by canyouseeme is a server operated by the cell phone company and your router is getting a NAT address, e.g. 192.168.x.x, 172.x.x.x, 10.x.x.x or 100.x.x.x. If that's the case then you will not be able to access your router from the internet (which I'm guessing is what the DDNS error message is telling you).
Unfortunately you are exactly correct! Thanks for confirming what I suspected, just didn't know the specific reasons. Was hoping to be able to connect to view/download security camera footage from 250 miles away. My internet connection is cell phone over ASUS router on both ends.
Thanks! Will look into that. But first I am going to try to get the old cameras to send me an email if motion is detected, supposedly they are capable of doing that. I just don't know if that will work through the ASUS/cell phone connection either. I tried a cellular trail camera but got thousands of pictures with tumble weeds and whirlwinds and could never get the PIR sensor sensitivity low enough.
