well - I installed QuTS 6.0.1, and to my dismay, ZeroTier is no longer able to run, and ZeroTier
wants you to run it in a docker (and I can’t find instructions for this). So I reinstalled Tailscale, which works fine, but QNAP has v1.4.0 in the App Center, and Tailscale is up to v1.98 ! I think it’s kind of important that QNAP updates the App Center to have a modern version of Tailscale running. Now, you can say “well - you can run QuWAN” - but you are not transfering a lot of data
between 2 QNAP systems running QuWAN for free. QuWAN super node is $15 per month to transfer 1 TB of data. And $24 a month for 2 TB of data. For people backing up their QNAP’s to remote QNAP sites, well - a lot of customers won’t be happy with this - so I will stick with Tailscale for now.
Just me complaining ! And hoping that QNAP updates the Tailscale version to a modern version.
I ran my Tailscale in a dedicated VM with 512MiB RAM because I would like to run it as a subnet router and don’t want to mess up the QNAP firewall and sysctl.
Up to QUTS 6.0.0 I had been using the long-depracated ZeroTier app, but this has finally stopped working under 6.0.1.
So, I have installed ZeroTier in a Docker container, which seemed to go OK, except that it gives a “ERROR: unable to configure virtual network port: could not open TUN/TAP device: No such file or directory” message and although ZeroTier Central can see my NAS, I can’t access anything remotely (unsurprisingly).
By opening a SSH prompt, entering the command “sudo chmod 0666 /dev/net/tun” and then restarting the container, it works fine. However, the tun device permissions revert back upon rebooting the NAS.
I have tried adding the command into a user start up script, but that doesn’t work either.
I believe that ZeroTier (covertly) makes some use of QVPN too,
