I do not currently have a VPN service, but I am looking in to one to get around some site blocks that my ISP has.
But I want to set up a VPN that operates at the level of my DSL modem or main router, so that the tunnel serves my entire LAN.
I imagine that I would configure my DSL modem or wireless router to use the VPN's tunnel. Thus, every device on my local net would simply see the desired VPN net natively... Without needing any VPN configuration on its own.
What is a good, basic, common way to get this done? I am not an expert, and I have mostly heard about VPNs that work at the level of a computer, not the whole net. But I have to believe that this "my whole LAN" method is commonly needed. How is it done?
