== WireGuard instance general configuration==

In this example, each interface’s general settings will be similar for all RUTOS devices. The difference will be in the assigned IP address. To set up the general configuration, follow these steps:

−

*When you have pressed [[File:Networking_rutx_manual_edit_button_v1.png]] go to the '''General Setup''' section

+

*When you have pressed [[File:Networking_rutx_manual_edit_button_v1.png]] near the WireGuard interface, go to the '''General Setup''' section

*'''Enable''' the interface

*Press [[File:Networking_rutx_manual_generate_button_v1.png]]

−

*Take note of the ~~device’s~~ public key

+

*Take note of the interface’s public key

*Set an IP address. For the '''server''' set '''10.0.0.1/24'''. For the '''clients''' set the IP to '''10.0.0.2/24 and higher'''. For example, client #1 – IP 10.0.0.2/24, client #2 – IP 10.0.0.3/24, and so on

Below is an example of the server’s WireGuard interface:

Endpoint = Server’s IP with WireGuard port. In this example, client #3 is inside the server’s LAN network.

The configuration could look like this:

−

AllowedIPs = 10.0.0.0/24, 192.168.1.0/24, 192.168.6.1/24

Endpoint = 192.168.9.1:51820

Line 80: Line 84:

===Server configuration===

+

Now we will need to add peers to the server's WireGuard interface.

+

====Peer 1 configuration====

Follow the steps below to configure settings for client #1:

*Enter the peer’s '''name''' (for example, client1) and press '''Add'''

−

*Set the peer's '''Public Key'''. To find it go to the ~~client’s~~ WireGuard interface general settings. There you will find the public key

+

*Set the peer's '''Public Key'''. To find it go to the client #1 WireGuard interface's general settings. There you will find the public key

−

*In the '''Allowed IPs''' add IP addresses and networks you ~~can~~ want to access. In this example, we will add client #1 WireGuard interface’s IP and its LAN network address

+

*In the '''Allowed IPs''' add IP addresses and networks you want to access. In this example, we will add client #1 WireGuard interface’s IP and its LAN network address

*Enable '''Route allowed IPs'''

*Press [[File:Save apply button.png]]

Line 91: Line 97:

====Peer 2 configuration====

−

For client #2 the steps are the same. Remember that the public key will be different and the allowed IPs list will slightly differ compared to ~~client 1 peer~~ configuration.

+

For client #2 the steps are the same. Remember that the public key will be different and the allowed IPs list will slightly differ compared to the previous configuration.

====Peer 3 configuration====

−

Since client #3 is a PC running WireGuard inside the server’s LAN the configuration will slightly differ compared to other clients. Follow these steps:

+

Since client #3 is a PC running WireGuard inside the server’s LAN the configuration will slightly differ compared to the other clients. Follow these steps:

*Enter the peer’s '''name''' (for example, client3) and press '''Add'''

*Set the peer's '''Public Key'''. To find it go to the WireGuard software inside the PC. In the '''Interface section below''' the '''Status''' indicator, you will find the public key

*Set the '''Endpoint host''' to the server’s public IP

−

*In the '''Allowed IPs''' parameter add IP addresses and networks you ~~can~~ want to access. In this example, we will only add the client's WireGuard interface’s IP. We will not add its LAN network because client 3 is already inside the server’s LAN

+

*In the '''Allowed IPs''' parameter add IP addresses and networks you want to access. In this example, we will only add the client's #3 WireGuard interface’s IP. We will not add its LAN network because client #3 is already inside the server’s LAN

*Enable '''Route allowed IPs'''

*Press [[File:Save apply button.png]]

+

The configuration could look like this:

+

[[File:Wireguard server to PC client peer v1.png|border|class=tlt-border]]

−

The ~~final results~~ could look like this:

+

The server interface's peers section could look like this:

[[File:Wireguard server to client all peers v2.png|border|class=tlt-border]]

Line 113: Line 121:

*Set '''Covered networks''' to the server’s WireGuard interface

*Set '''Allow forward to destination zones''' and '''Allow forward from source zones''' to WireGuard

+

*Press [[File:Save apply button.png]]

The configuration could look like this:

[[File:Firewall_for_wireguard.png|border|class=tlt-border]]

Line 123: Line 132:

You will see the interface's and its peers' information. In the peer information section look for the latest handshake (a line below allowed IPs). If you can see “latest handshake” it means the peer made a connection to the server.

This is an example of how the command’s output could look like:

−

[[File:WG show output v1.png|border|class=tlt-border]]

+

[[File:Teltonika Networks WG show output v3.png|border|class=tlt-border]]

+

'''Note:''' if you do not see the latest handshake line, then try pinging the server’s Public IP (the one specified in the Endpoint Host parameter) and/or server’s VPN IP (in this example it would be the 10.0.0.1) from each peer.
