Stop Rolling Your Own VPN Configs: Practical WireGuard with systemd-networkd on Linux
WireGuard has become the go-to VPN for Linux homelabs and servers because it's fast, simple, and kernel-native. But many people still rely on wg-quick and ad-hoc .conf files that are easy to get wrong under automation.
systemd-networkd gives you a cleaner, declarative path that integrates directly with the rest of your systemd setup. No extra services, no PostUp/PostDown scripts to maintain, and native reload semantics.
This guide shows the exact files and commands that work on Debian 12 and Ubuntu 22.04/24.04 today.
Why systemd-networkd over wg-quick?
