OpenSource-Ghost The local network and ISP can see the connections to the IP addresses. They don't need the DNS queries to find the specific IP addresses that are used. It's not clear what the benefit would be of using the Private DNS server for looking up the VPN IP address since it's very obvious where you're connecting. You're talking about doing something sophisticated and yet not doing the basics. Private DNS only helps against unsophisticated, very passive surveillance and it has significant drawbacks such as being global rather than per-user like VPN configuration. You should avoid Private DNS in combination with VPNs especially when using multiple profiles.
Our FAQ doesn't currently try to provide much advice on these topics, especially since people will then want to debate it and attack the project over it.
