Image link is broken?
Should work now, if not hit refresh or go to http://img3.exs.cx/img3/5382/ExplinationEncryption.jpg
:lol: Haha. Well, now that I can see it, I know I haven't the foggiest idea whether or not it's possible, so I'll just move along.
I should be possible somehow... maybe some VPN or ssh tunnel? if you know the IP of the machine you're connecting to and there's no firewall/proxy it should be quite easy. Not sure how to set it up though, I'd look/google for an tutorial on ssh.
I would suggest that you take a look at something like this link –
It is a good how to on setting up a Linux based VPN
Yes, a VPN would do what you need. However, please be aware that a VPN will only encrypt your data to that one server. All other traffic on your wireless network would be sniffable.
Just a heads up.
