I’m heading off to Zürich for the fourth time this year. If you travel internationally, you know that certain services (e.g. Netflix) don’t work overseas. One solution is to use a VPN server located “back home” (presumably there are services that don’t work in the US!) There are free and commercial VPN providers of course, but it’d be nice to have full control of your own server, and to only run it while you’re abroad.
