Why doesn't VPN DNS override adapter DNS?
There are DNS servers that help me get around my work network. But when I'm away from the office I only want to use these DNS servers if I'm connected to VPN, else I want to pick up the default DNS.
There's an option to configure DNS addresses for VPN connections. However, these never get used as far as I can tell. As long as the DNS server I want to use is missing from my adapter's (e.g. wifi or ethernet) DNS settings, I will not ever see the machines whose addresses are resolved by my work network's DNS.
I've seen this reported other places but no solution. Is it possible that this could be fixed in a future update? As for now, I have to switch "locations" (i.e. Apple menu --> Location) instead of having one setting that works everywhere. That, or use IP addresses instead of computer names.
Alternatively, I'd like the DNS servers that I add manually to be *in addition* to the servers that are picked up automatically. Right now, if I add my work DNS, then I also have to add a public DNS just to get to the internet when outside of work. I'd like to add my work DNS to my ISP or home network's DNS.
