LXC Containers

I used a combination of these two docs to enable the TUN device in an LXC containter.

https://www.cloudhosting.lv/eng/faq/How-to-enable-tun-tap-inside-LXC

https://forum.proxmox.com/threads/passing-usb-device-on-lxc-not-working-after-upgrade-to-7-0.92178/#post-401606

Use nano/etc/pve/lxc/123.conf to add the following lines to the LXC boot config.

lxc.cgroup2.devices.allow: c 10:200 rwm
lxc.mount.entry: /dev/net dev/net none bind,create=dir

Add the following to /etc/rc.local inside the container

if ! [ -d /dev/net ];then
 mkdir /dev/net
fi
if ! [ -c /dev/net/tun ]; then
 mknod /dev/net/tun c 10 200
 chmod 666 /dev/net/tun
fi
