This little box does exactly what it says on the tin. Its simple, and it has no extra features that aren't necessary. Its not a modem router, and it doesn't need it. It plugs right into the back of an existing router, and adds a simple but strong VPN solution to an existing (or new) network. Don't buy it if you want to use Open VPN or IKEv2, though, as they require a cloud-based portal, but if L2TP is what you are after, then this little box does it admirably.
