Bare metal installation, OS 6.12.15, running Wireguard and Tailscale services.

I had a power outage and UPS issued AFAIK a clean shutdown for Unraid server. Router was not affected by the outage. After restarting the server Windows VM's cannot ping, access shares or the Unraid GUI (for the record, I have not really used the Vm's for accessing the GUI, but I believe it has been accessible before). The VM's network are vhost0/virtio-net and receive IP address from the router by DHCP. Everything else on the LAN is accessible except the Unraid host and it's services. I tried a new linux VM with same network settings and it also fails to ping and access the host GUI.

I can RDP the VM's from LAN, but if I try RDP trough Wireguard or Tailscale, the session fails. One of the Windows VM's is DVR and it is also inaccessible via mobile app through VPN where it used to work before the shutdown. On LAN the mobile app connects fine.

My laptop and mobile phone connects to the server, and services, without issue through Wireguard and Tailscale.

I have restarted the router and Unraid server. No luck.

I'm at loss here. Something with Unraid routing? I can't figure out if and what has changed.

Diagnostics attached.

I seem to have fixed this. I enabled network bridging on eth0, changed VM's network to br0. Also changed from macvlan to ipvlan on docker settings. So far so good.
