I love his topics as they have all proved to be very helpful. With the different ways he has illustrated the methods to remotely access unRaid GUI and VMs, I have been waiting for him to help with a solution to get around Carrier Grade NAT. With all of my own domain, DuckDNS domian/ subdomains, as well as some from afraid dns I still can not push through the CNAT. All following his guides over the past few years of course.
I have tried OpenVPN docker, NGINX proxy Manager, Zerotier, and a few others. When I had a static IP it was no issue, but sadly I can no longer get a static IP address from my ISP. I know this is right up his alley and he would most likely be the one with the solution.
