[TriLUG] Getting around ISP port blocks with VPN?

[Brian via TriLUG]

Hey Gang,

I currently have business-class cable internet.  I've been thinking 
about dumping it for residential fiber.  What I'm trying to figure out 
is the best way to deal with possible port blocking that might be in 
place on the residential services.  Having a secured tunnel to some 
public interface out in the cloud somewhere seems like a possible 
approach, but I don't really know what words to use to describe it to 
Google well enough to find people selling such a thing.

Presently my home server/firewall simply has a public interface with 
ports open for the services I host.  What I imagine is instead there 
being a VPN (or some other secure tunnel) to a server in the cloud 
somewhere through which all my server traffic (i.e. connections 
initiated from outside) would be routed, thereby sidestepping any port 
blocks on my local ISP.

Is this a thing?  What do you call it?  Does anybody on the list already 
do something like this?

Thanks,
-Brian
