Take a look at this: https://tailscale.com/kb/1133/proxmox
especially this: https://tailscale.com/kb/1130/lxc-unprivileged

you have to add the following to the lxc config file eg. /etc/pve/lxc/112.conf

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