| Workaround from snabb, https://github.com/systemd/systemd/issues/6076 | |
| My current workaround is to do the following tricks every time I start my workplace VPN: | |
| 1. Find out the link number (a.k.a. interface index) of the ISP interface: systemd-resolve --status or ip l. | |
| 2. Connect the VPN. | |
| 3. Remove DNS settings from the ISP interface (using the link number from step 1) by sending a D-Bus command to systemd-resolved. This is an example using link number 2: sudo busctl call org.freedesktop.resolve1 /org/freedesktop/resolve1 org.freedesktop.resolve1.Manager SetLinkDNS 'ia(iay)' 2 0 | |
| 4. Inspect with systemd-resolve --status to ensure that only the correct DNS servers are there. | |
| Apparently there isn't any simple cli tool for managing systemd-resolved's settings. That busctl command isn't very user-friendly. :) |
