It's an easy thing to chase for an evening before realizing the router did everything right and the problem sits one layer further out, on the carrier's network. This explainer covers what carrier-grade NAT (CGNAT) actually is, why 5G home internet and satellite providers default to it, what it does and doesn't break for VPNs and remote access, and the workarounds people actually use to get around it.</p>
