Many thanks for all your work on the public server!
As you are currently having trouble with your dynamic IP would you consider signing up for a free DynDNS service?
That way we could all configure our clients to connect to something like cdfalcon.noip.me and the DNS would always resolve that into your current server IP address at that time.
I have good experience with this free provider: https://www.noip.com/sign-up, but because it’s free they ask you to solve a Captcha once a month.
Keep up the good work!!
