WireGuard support for Synology NAS
==================================
This package adds WireGuard support for Synology NAS drives. It provides the
WireGuard kernel module and the ``wg``/``wg-quick`` commands.
Disclaimer
----------
You use everything here at your own risk. I am not responsible if this breaks
your NAS. Realistically it should not result in data loss, but it could render
your NAS unaccessible if something goes wrong.
If you are not comfortable with removing your drives from the NAS and manually
recover the data, this might not be for you.
Compatibility list
------------------
The following drives have been tested:
========= ========= =========== ===========================
Model Platform DSM Version Is working?
--------- --------- ----------- ---------------------------
DS114 armada370 *N/A* No (Kernel version too old)
DS115j armada370 *N/A* No (Kernel version too old)
DS213j armada370 *N/A* No (Kernel version too old)
DS213j armada370 *N/A* No (Kernel version too old)
DS214play armada370 *N/A* No (Kernel version too old)
DS214se armada370 *N/A* No (Kernel version too old)
DS216se armada370 *N/A* No (Kernel version too old)
DS218j armada38x 6.2 Yes
DS414slim armada370 *N/A* No (Kernel version too old)
RS214 armada370 *N/A* No (Kernel version too old)
========= ========= =========== ===========================
The minimum required kernel version is 3.10. If you have a kernel version lower
than that, WireGuard will not work. You can check your kernel version by
logging in through SSH and running the ``uname -a`` command.
Installation
------------
Check the `releases <https://github.com/runfalk/synology-wireguard/releases>`_
page for SPKs for your platform. If there is no SPK you have to compile it
yourself using the instructions below.
1. In the Synology DSM web admin UI, open the Package Center and press the
*Settings* button.
2. Set the trust level to *Any publisher* and press *OK* to confirm.
3. Press the *Manual install* button and provide the SPK file. Follow the
instructions until done.
Now you just need to figure out how to configure WireGuard. There are lots of
good guides on how to do that.
To put my WireGuard configuration on the NAS, I used SSH and created a
``wg-quick`` configuration in ``/etc/wireguard/wg0.conf``. Then I opened the
*Control panel*, opened the *Task scheduler* and created *Triggered task* that
runs ``wg-quick up wg0`` on startup.
Compiling
---------
I've used docker to compile everything, as ``pkgscripts-ng`` clutters the file
system quite a bit. First create a docker image by running the following
command in this repository:
.. code-block:: bash
git clone https://github.com/runfalk/synology-wireguard.git
cd synology-wireguard/
sudo docker build -t synobuild .
Now we can build for any platform and DSM version using:
.. code-block:: bash
sudo docker run --rm --privileged --env PACKAGE_ARCH=<arch> --env DSM_VER=<dsm-ver> -v $(pwd)/artifacts:/result_spk synobuild
You should replace ``<arch>`` with your NAS's package arch. Using
`this table <https://www.synology.com/en-global/knowledgebase/DSM/tutorial/General/What_kind_of_CPU_does_my_NAS_have>`_
you can figure out which one to use. Note that the package arch must be
lowercase. ``<dsm-ver>`` should be replaced with the version of DSM you are
compiling for.
For the DS218j that I have, the complete command looks like this:
.. code-block:: bash
sudo docker run --rm --privileged --env PACKAGE_ARCH=armada38x --env DSM_VER=6.2 -v $(pwd)/artifacts:/result_spk synobuild
If everything worked you should have a directory called ``artifacts`` that
contains your SPK files.

I based a lot of this work on
`this guide <https://www.reddit.com/r/synology/comments/a2erre/guide_intermediate_how_to_install_wireguard_vpn/>`_
by Reddit user `akhener <https://www.reddit.com/user/akhener>`_. However, I had
to modify their instructions a lot since my NAS has an ARM CPU which made cross
compilation a lot trickier.
