How To Enable WireGuard on FreeNAS 11.3

  3 minute read

Google Drive and G Suite are widely used tools for creating and sharing documents, spreadsheets, and presentations with team members. While cloud-based tools have inherent backups and replications included by the cloud provider, certain users may require additional backup or archive capabilities. For example, companies using G Suite for important work may be required to keep records for years, potentially beyond the scope of the G Suite subscription. FreeNAS and TrueNAS offer the ability to back up Google Drive easily, using the built-in cloud sync.

This blog will explain how to set up Google Drive sync with FreeNAS 11.3, as well as provide a few caveats and workarounds when backing up Google Docs and other Google created content.

Setting up Google Drive credentials

Set up the credentials under System > Cloud Credentials.

WireGuard is a popular option in the VPN marketplace due to its speed, simplicity, and modern cryptography standards. Starting with FreeNAS version 11.3-RC1, it is possible to connect your NAS directly to a WireGuard network with a few easy steps.

We get started on this by creating some custom tunables to enable the service and give it a default interface. To do this you must first navigate to System > Tunables > Add.

Enable the WireGuard service by adding “wireguard_enable” -> “YES” in rc.conf.



Next, create another tunable and add “wireguard_interfaces” -> “wg0” in rc.conf.



When finished, you should have the following two variables set and enabled.



Next, we will need to create a post-init script that will place the WireGuard config into the correct location at startup. Navigate to Tasks -> Init/Shutdown Scripts -> Add.

Create the following command and set it to run at post-init:

mkdir /usr/local/etc/wireguard && cp /root/wg0.conf /usr/local/etc/wireguard/wg0.conf && /usr/local/etc/rc.d/wireguard start

You can configure the /root/wg0.conf file and apply a WireGuard configuration to attach to whatever WireGuard network you define. It can be a single point-to-point to anything running WG, or even with full routing. Example use cases are:

  • Access data on a NAS from your Remote Laptop
  • Linking NAS to NAS for replication
  • Attaching a managed NAS to a remote network
  • Access to your NAS from your smartphone


We need to create the /root/wg0.conf which will contain the specific WireGuard configuration to apply at boot. This configuration is beyond the scope of this article, but there are quickstart guides and tutorials available online as well as the built-in wg-quick manpage.

Once you have a valid /root/wg0.conf, rebooting the system should bring up the WireGuard interface, and you’ll see a wg0 device in the output of ifconfig.



Congratulations, you have successfully linked your FreeNAS system to a secure WireGuard tunnel!
