Zerotier Synology Nas

Hi

I’m a beginner so sorry if it a stupid question.

I’m trying to go through this guide:

I have done the ‘‘ENABLE SSH access on your NAS’’ step and now I’m stuck on ‘‘Create a persistent TUN’’.
When I’m trying to do this step:
‘‘Run script once to create a TUN’’

I got this error: insmod: ERROR: could not insert module /lib/modules/tun.ko: File exists

Terminal:

root@NAS1:~# echo -e ‘#!/bin/sh -e \ninsmod /lib/modules/tun.ko’ > /usr/local/etc/rc.d/tun.sh
root@NAS1:~# chmod a+x /usr/local/etc/rc.d/tun.sh
root@NAS1:~# /usr/local/etc/rc.d/tun.sh
insmod: ERROR: could not insert module /lib/modules/tun.ko: File exists
root@NAS1:~#

Can anyone help please ?

Did you try the next step, i.e. check if the TUN exists?

It kind of looks like it was already setup.
