I use public Wifi constantly when I'm away from home/office. I'm contemplating setting up a home VPN, which my ipod touch and laptop could communicate with via VPN to protect my requests from prying eyes, whether it is through the owner of the public wifi or some script kiddie running firesheep.
Being somewhat ignorant of VPNs, Im wondering if they by default route all requests through the VPN?
I.e., If I connect to public wifi, connect to vpn, and visit a site in the browser, would I expect my request to be routed through the VPN tunnel, and then my home network makes the request and returns the result? Or does HTTP traffic go through the public Wifi, and only POP etc are secure?
Any recommendations for good/easy home VPN?
