I have signed up with you guys, and the service is great. However, I have five desktop PC's in my home. I want to be able to Remote Desktop them, but I only have 1 Dynamic IP from my internet provider.

Do I need to purchase additional dynamic IP's from my internet provider, as I am only able to connect to one of my computers using your DNS hostname service. Not sure what else I need to do, so that I can connect to all of my computers in my home. Hope you can shed some light in this for me. I read your tutorials online, and nothing worked. I also have port forward active on my router with is a UNIFI system. Thank you

No need for additional IPs, just use port forwarding in your router to translate your domain name + chosen port number to the appropriate lan-ip:3389.
