WireGuard support for Synology NAS
==================================
This package adds WireGuard support for Synology NAS drives.

NAS.


Compatibility list
------------------
The following drives have been tested:

===== ========= =========== ===========
Model Platform  DSM Version Is working?
----- --------- ----------- -----------
D218j armada38x 6.2         Yes
===== ========= =========== ===========


Compiling
---------
I've used docker to compile everything as ``pkgscripts-ng`` clutters the file
system quite a bit. Start by setting up a new docker container and enter a bash
prompt inside it:

.. code-block:: bash

    sudo docker create -it --privileged --name synobuild ubuntu
    sudo docker start synobuild
    sudo docker exec -it synobuild bash

Now we can setup the build toolchain inside the Docker container:

.. code-block:: bash

    apt-get update
    apt-get install git python3 wget ca-certificates
    git clone https://github.com/SynologyOpenSource/pkgscripts-ng
    mkdir source
    git clone https://github.com/runfalk/synology-wireguard /source/WireGuard

The next step is figuring out which platform and DSM version to compile for.
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 how the next command should look like. In my case it's:

.. code-block:: bash

    pkgscripts-ng/EnvDeploy -p armada38x -v 6.2

Now we can build an SPK package:

.. code-block:: bash

    pkgscripts-ng/PkgCreate.py -p armada38x -v 6.2 -S --build-opt=-J --print-log -c WireGuard

There should now be an SPK in ``/result_spk``

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 which made cross
compilation a lot trickier.
