Networking can feel intimidating at first, but with the right approach you can turn a simple virtual server into a capable routing backbone that spans from your home lab to a cloud VPS.

VyOS 1.5 fully supports WireGuard, making it an excellent choice for organizations looking to interconnect multiple datacenters or sites. In this guide, we'll show you how to set up a site-to-site WireGuard tunnel on VyOS 1.5. We'll cover routing, firewall configuration, and best practices. By the end, your sites will be securely connected over the internet with traffic routed effectively between LANs.
