Homelab WireGuard VPN
WireGuard is a fast, modern VPN protocol. It is the right choice for remote access to a home network — simpler to configure than OpenVPN and faster than most alternatives.
All configuration examples show common setups. Review each command — especially the iptables forwarding rules and key file permissions — before applying them to your system, and make changes in a maintenance window.
When to Use
- Setting up WireGuard server on a Raspberry Pi, Linux host, pfSense, or router
- Generating WireGuard keypairs and writing peer config files
- Configuring remote access from a phone or laptop to a home network
- Explaining split tunneling (route only home traffic) vs full tunnel (route all traffic)
- Troubleshooting WireGuard connections that will not come up
- Automating peer configuration generation for multiple clients

The server knows each client's public key.
