Once WireGuard is installed, you can check that the installation succeeded by running: wg , if you get no output it's all good. In order to check that the WireGuard kernel module has loaded you can run sudo modprobe wireguard .

How safe is WireGuard?

WireGuard is highly secure, but it's not designed with privacy in mind. At time of writing, the biggest privacy weakness that WireGuard has is how it assigns IP addresses. When you connect to a VPN service using OpenVPN or IKEv2, you're assigned a different IP address each time.

How does WireGuard VPN Work?

WireGuard uses modern cryptography and network code to create an encrypted tunnel between two devices. Using some clever strategies, it even works when the client device's IP address changes. For example, you can switch from mobile data to Wi-Fi without waiting thirty seconds for the VPN to reconnect.

Does WireGuard hide IP address?
