==Introduction==

'''WireGuard''' is simple, fast, lean, and modern VPN that utilizes secure and trusted cryptography.
This page will show you an example on how to configure a basic tunnel between WireGuard interface and its peers.

==Prerequisites==

For this example you need:
<li>Two RUTOS devices (this example will be written with RUTX09 and TRB141 in particular)</li>
<li>An end device to configure devices (PC, Laptop, Tablet or Smartphone)</li>
<li>One end device must have <b>Public</b> IP address</li>

==End results==

In the end there will be created a tunnel between RUTX09 and TRB141.
RUTX09 will have 10.0.0.1 and TRB141 will have 10.0.0.2 tunnel IP addresses.

==WireGuard Instances==

To create Instance enter its name and click the <b>Add</b> button.
Then click the <b>Edit</b> [[File:Networking_rutx_manual_edit_button_v1.png]] button to configure it.

In this example Instance is named by its device name to make it easier to follow images.

====TRB141 Example====

==Instance Configuration==

The following part of example applies to both devices.

Before editing any fields click [[File:Networking_rutx_manual_generate_button_v1.png]] button
to generate Public and Private keys.

After that you need to Enable this instance and in the <b>Listen Port</b>
field enter your desired port. WireGuard by default uses <b>51820</b> port which will be used in this example.

Lastly you need to enter IP Address for instance. As mentioned in the beginning, RUTX09 will have 10.0.0.1 and TRB141
will have 10.0.0.2 IP addresses.

<b>Note:</b> enter IP address <b>and</b> its mask e.g. <b>10.0.0.1/24</b>

====RUTX09 Example====

<b>Note:</b> fields with numbers <b>1</b> and <b>2</b> will be used later when configuring remote peers.

====TRB141 Example====
----
[[File:Networking_wireguard_configuration_example_interface_general_trb141_v2.png|border|class=tlt-border]]

<b>Note:</b> fields with numbers <b>3</b> and <b>4</b> will be used later when configuring remote peers.

==Peers==

Until now you have configured WireGuard instance itself, now you need to configure Peers
which are going to connect to those instances.

To create Peer enter its name and click the <b>Add</b> button.
Then click the <b>Edit</b> [[File:Networking_rutx_manual_edit_button_v1.png]] button to configure it.

One Peer for each device will be created:
<li><b>RUTX09</b> will have a Peer named <b>trb1peer</b></li>
<li><b>TRB141</b> will have a Peer named <b>rutxpeer</b></li>

====RUTX09 Example====

====TRB141 Example====

==Peers Configuration==

===General Setup===

In the <b>General Setup</b> section you need to enter <b>Public Key</b> and <b>Allowed IPs</b> from the Remote instance you want to connect to.

In this example a peer from RUTX09 (named <b>trb1peer</b>) needs to connect to TRB141, which means <b>trb1peer</b>
will enter Public Key and Allowed IPs from TRB141.

<b>Note:</b> the numbers in the images below represent a <i>number of field</i> from which that value
was taken from the images in [[WireGuard_Configuration_Example#Instance Configuration]].

====TRB141 Example====
----
[[File:Networking_wireguard_configuration_example_interface_peers_configuration_trb141_v2.png|border|class=tlt-border]]

===Advanced Setup===
----

Lastly atleast one device has to enter Remote instance Public WAN IP address. Enter IP address, save and move to the [[WireGuard_Configuration_Example#Testing Configuration]].
