I see, so in your opinion are there any downside to using vpn over ssh/vnc? Or perhaps a better question, why would I want to use ssh/vnc?

thanks again

If you only want to securely vnc, I don't think moving from ssh to vpn is going to provide you any tangable benefit and it's probably going to be quite an effort to set up (it was for me). If you want to tunnel all your traffic, vpn is the right tool for the job.

Yep, as cpm said.

There are two main reasons for using VPN:
a) You want to tunnel all your traffic through somewhere else, for some reason (i.e. accessing internet sites through somewhere else)
b) You need to access an internal network from outside. E.g. a company network. This may not be possible just with SSH.

Thanks Guys! For now I think I'm happy the way things are. But I think at some point it might be nice to have my traffic tunneled and secure when on public wifi (without setting up the ssh socks/proxy stuff all the time).

But it's nice to know how they to protocols overlap and their main difference. Of course probably simplified, but I can do more research when I need it.
