I know very little about exactly how these things work.  However, I do periodically use hotspotvpn on my laptop when I'm on the road.  Let's say I wanted to run some server process on the laptop while I was connected to the tunnel.  Let's say I own the domain ronsspecialserver.com.  I THINK all I would have to do is run the DDNS client after establishing the tunnel.  That would map my current public IP over to ronsspecialserver.com at that moment in time.  Then, anyone on the internet should be able to access ronsspecialserver.com and it should hit my machine.  Other than possible problems with the acceptable use policy of the vpn provider, am I missing anything here?

Sincerely,

Ron
