One downside of PureVPN's tunneling all traffic is that it does not allow use of the local DNS settings. For most people and most needs that is good, but systems like PiHole that block DNS queries for certain sites get bypassed because those DNS servers are on the local network. It would be great if we could specify the DNS server, even if it is our external IP address (so we'd have to port forward the DNS query back to our local server). This is not that unusual since Raspberry Pi systems are <US$50 to set up and VMs are free.
