I’m a big fan of Tailscale and when I’m not at home I still like to use the Pi-hole I have setup at home to block ads and malicious sites. The way I manage this is to set my DNS server to the TS IP 100.69.187.53 for my Pi-Hole.
This works well unless I’m out and about and on public wifi, especially if there is a captive portal, sometimes “Things Fall Apart”* as the auth may need to use local DNS. You can solve this by –> Settings –> Wi-fi –> Details –> DNS (change the DNS) auth the portal and then change everything back.
Of course there is a way to script this so I created the following two scripts in
#!/bin/bash networksetup -setdnsservers Wi-Fi 220.127.116.11
#!/bin/bash networksetup -setdnsservers Wi-Fi 100.69.187.53
Don’t forget to make sure the scripts are in your path and to mark them
*I found out about the book from title of the amazing album by The Legendary Roots Crew of the same name here’s a review of “Things Fall Apart”
