How to Use WireGuard Setup for Linode?

The following is required in order to configure a WireGuard on a Linode:

Prerequisites: An instance of Linode running the WireGuard kernel module, A VPN gateway for WireGuard, Between the VPN gateway and the Linode instance, a VPN tunnel, The preferred WireGuard client software, and Between the VPN gateway and the intended destination, a VPN tunnel.

Steps Needed

1. Installing the WireGuard kernel module on the Linode instance requires running the following command:

2. We must run the following command to enable the WireGuard kernel module after it has been installed.

3. The next step is to set up a VPN gateway. Make a new configuration file named wireguard.conf on the VPN gateway.

4. Add the following lines to the wireguard.conf file:

5. Now, include the below route configuration to the VPN gateway:

6. Then, add the following line to the end of the file:

7. We must now establish a WireGuard connection between the VPN gateway and the Linode instance after setting up the VPN gateway. Make a new configuration file named wireguard.tunnel 10.0.2/24 on the Linode instance. Next, give the Linode instance the following route configuration: route 10.

8. Installing the WireGuard client software at the intended location is the final step. Install the WireGuard client software at the intended location. Launch the WireGuard client application and establish a connection with the Linode instance. The WireGuard tunnel will now be broadcast by the Linode instance. Now, the target destination’s WireGuard client program may establish a connection to the WireGuard tunnel.

Conclusion

Although WireGuard is a strong tool, it is readily abused. We must make sure we know how WireGuard operates and how to set it up correctly if we are installing it on a Linode. Network security problems may be readily caused by incorrectly configured WireGuard.
