Hi,
I have an issue with the permission of the tunnel card. When the UDM-Pro reboot the Zerotier-one service start but can’t modify the route apply to the tunnel card. the Site to Site is UP in the Zerotier web page, but there’s no traffic.
If I chmod 766 /dev/net/tun and systemctl restart zerotier-one
Everything is back and running.
Is there a way solve this
Thanks a lot
