Wireguard
#########
| Testdate: 2023-08-31
| Version: 1.4-rolling-202308240020
This simple structure show how to connect two offices. One remote branch and the
central office.
********
Topology
********
The topology have a central and a branch VyOS router and one client, to
test, in each site.
.. image:: _include/topology.png
:alt: Ansible Example topology image
*************
Configuration
*************
Set the local subnet on eth2 and the public ip address eth1 on each site.
Central
.. literalinclude:: _include/central.conf
:language: none
:lines: 1-2
Branch
.. literalinclude:: _include/branch.conf
:language: none
:lines: 1-2
Next thing to do, is to create a wireguard keypair on each side.
After this, the public key can be displayed, to save for later.
.. code-block:: none
vyos@central:~$ generate pki wireguard key-pair
Private key: cMNGHtb5dW92ORG3HS8JJlvQF8pmVGt2Ydny8hTBLnY=
Public key: WyfLCTXi31gL+YbYOwoAHCl2RgS+y56cYHEK6pQsTQ8=
After you have each public key. The wireguard interfaces can be setup.
Central
.. literalinclude:: _include/central.conf
:language: none
:lines: 4-12
Branch
.. literalinclude:: _include/branch.conf
:language: none
:lines: 4-12
To reach the network, a route must be set on each VyOS host.
In this structure, a static interface route will fit the requirements.
Central
.. literalinclude:: _include/central.conf
:language: none
:lines: 14
Branch
.. literalinclude:: _include/branch.conf
:language: none
:lines: 14
*********************
Testing and debugging
*********************
After all is done and commit, let's take a look if the Wireguard interface is
up and running.
.. code-block:: none
vyos@central:~$ show interfaces wireguard
Codes: S - State, L - Link, u - Up, D - Down, A - Admin Down
Interface IP Address S/L Description
--------- ---------- --- -----------
wg01 192.168.0.1/24 u/u VPN-to-Branch
And ping the Branch PC from your central router to check the response.
.. code-block:: none
vyos@central:~$ ping 10.0.2.100 count 4
