It is intentionally concise in the first release, but it keeps the shape of the final article visible.</p> <h2>Scope</h2> <ul> <li>Peer identity and public key mapping</li> <li>AllowedIPs as both routing policy and access boundary</li> <li>Site-to-site, remote access and hub-and-spoke patterns</li> <li>NAT traversal and endpoint roaming</li> <li>Operational risks around key rotation and route leakage</li> </ul> <h2>Reference Architecture</h2> <pre><code>flowchart LR Engineer[Engineer Laptop] --&gt; Edge[WireGuard Edge] Branch[Branch Router] --&gt; Edge Edge --&gt; Services[Internal Services] Edge --&gt; Observability[Logs and Metrics] </code></pre> <h2>Future Notes</h2> <p>The complete article should compare WireGuard with IPSec and SSL VPN designs, then document operational practices for routing, monitoring and incident response.</p>
