I'd like to be able to access my home computer/devices from anywhere with remote desktop on my tablet, I tried using a free DDNS to see if that would work but I realized my router is behind NAT so the IP that the public sees is not my real IP which means... Trying to connect through the domain name the DDNS gave me is not possible, or at least that's the conclusion I came to by trying for hours.
I went on and purchased a subscription to CyberGhost VPN but then I didn't see anything that indicates I could achieve what I wanted with that so I just went for the refund (yeah, not the smartest of cookies haha)
I know this is possible with a static IP but I'm not sure if I can do it without it. Is this possible and if yes? What are the steps and services I will need?
