How PiVPN Works
PiVPN utilizes the WireGuard protocol to establish a secure VPN connection. WireGuard is a modern and efficient VPN protocol that offers fast speeds, low latency, and strong encryption. PiVPN automates the configuration and management of WireGuard, making it easy to set up and use.
When you connect to a PiVPN server, your device creates a secure tunnel to the remote network. All data transmitted through this tunnel is encrypted, ensuring privacy and security. PiVPN also supports split tunneling, allowing you to selectively route specific traffic through the VPN while excluding others, providing flexibility and control over your network connections.
PiVPN with WireGuard Split Tunneling
Split tunneling is a networking technique that allows you to route some of your internet traffic through a VPN while allowing other traffic to go through your regular internet connection. This can be useful if you want to protect your privacy on certain websites or services while still being able to access your local network and other websites without the overhead of the VPN.
PiVPN is a popular open-source VPN software that can be used to set up a VPN server on a Raspberry Pi. PiVPN can be configured to use WireGuard, a modern and fast VPN protocol. In this guide, we will show you how to configure PiVPN with WireGuard split tunneling.
Prerequisites
