systemd.resolved
vitualbox -NAT- vm1:pfsense -INTERNAL- vm2:ubuntu 20.04.5
I follow instrution in pdf to init the cluster
After a moment or after a reboot
ping google.com # return an error
Workaround: 8.8.8.8 in /etc/resolv.conf
but systemd.resolved overide my config on reboot
I try calico network troubleshoot in
/etc/NetworkManager/dispactcher.d/calico.conf
without succes.
Could I have any tips how debug DNS in systemd.resolved ?

Hi @bashtop86,
For vbox VMs I would recommend a single bridged adapter per VM, ensuring that either DHCP or static VM IP addresses are not from the 192.168.0.0/16 subnet (otherwise they overlap with the Pod subnet managed by the Calico network plugin), and vbox promiscuous mode is enabled to allow all inbound traffic on each VM.

Tanks for your fast response.
My admin machine finally broken too,
so I figure out it was a mist-configuration on my pfsense0
