That UnoDNS service is not a VPN provider. It is an alternative DNS provider, and proxy service.
As asked elsewhere what is it you are trying to achieve?
If you simply want to get around geo-blocks for streaming media, then the UnoDNS service will do that.
If you want to hide your location for other reasons then the UnoDNS service will not work for you.
Setting up a VPN if you already have a provider, and a router capable of connecting to a vpn should be fairly straight forward (separating traffic based on what device it is from may be more tricky). But a VPN may well not be the correct solution for your problem.
