After the recent Copyright/File Sharing law coming into effect, I wanted to sign up to a VPN service such as that offered on Privacy.io. However, I have two PCs on my home network and one QNAP NAS device, so I want to cover all the devices on my home network with just the one paid VPN service.
Which leads me to my noob question: I have very limited knowledge when it comes to VPN/routers/suchlike, so I was wondering if there is a suitable modem/router that I can enter my VPN PPTP credentials into that will cover all the devices connected to it? I ideally require the router to contain a built in ADSL2+ modem, gigabit Ethernet ports and wireless 802.11n connectivity.
I apologise for my ignorance in the matter, but any and all help would be much appreciated!

Thanks in advance,
Katz.
