Enable ZeroTier 1.6.6 ProxMox 6.4 LXC Container

If you are looking to create a zerotier interface into an unprivileged lxc container in proxmox, you can simply update the lxc container as follows:

  1. Open the config of the container. It is usually located under /etc/pve/lxc.
sudo nano /etc/pve/lxc/XXX.conf
  1. Then add the following line and save the config file.
lxc.mount.entry: /dev/net/tun dev/net/tun none bind,create=file
  1. Reboot the container
  1. run zerotier-cli listnetworks and you should see that the port_error has now disappeared.

Also, this client should now be able to ping other members in the same ZeroTier network and vice versa.
