Have two sites/subnets connected via pfSense machines/tailscale, global DNS of 1.1.1.1.
If I startup or make any changes to tailscale configuration, machines become unreachable by machine name for a few hours. Subnet IP’s and Tailscale IP’s remain reachable across sites just fine, but machine names don’t work. If I wait a few hours they seem to start working again.
Any idea on the cause and/or how to prevent this? Have tried flushing DNS, restarting tailscale on each pfsense box, resetting states, etc.
Thanks!
