Re: Own VPN?
"Setting up your own VPN might look like a great solution but it is not as clear cut. For a start you probably end up renting a "machine" somewhere for always-on connectivity and a fixed IP address which will cost more and/or also have the question of who has physical access to it."
For starters you may already have a router capable of being a VPN concentrator already. If not then DD-WRT, Tomato, pfSense, Netgear, Draytek and many others can. You do not need a static IP either - there are loads of dynamic DNS operators available. Most routers will have a built in client for DDNS as well.
So, no: don't think you should rent a machine in the cloud unless you know what you are doing. Subscribe to /r/homenetworking on Reddit or the pfSense forums or whatever and find out how to get your home network in shape first. The only reason I can think of to not host your own VPN at home is if your ISP blocks all inbound access.
