No NAT, no per-site static IP requirement, no recurring vendor fee.</p> <p><strong>Terminology note:</strong> the underlying technique here is a <strong>site-to-site VPN</strong> — a permanent, routed tunnel connecting two networks. &ldquo;Multi-site&rdquo; just means using that same technique more than once: a hub site runs a separate site-to-site tunnel to each additional location. Two sites is the base case (one tunnel, one peer on each end); three or more is that same setup repeated, with the hub acting as the common point. Nothing about the core configuration changes as sites are added — Step 2 through Step 5 are simply repeated per additional spoke.</p>
