A double NAT occurs when you plug your personal router into an ISP-provided modem/router combination unit.

When multiple routers handle network traffic, or your Internet Service Provider (ISP) uses Carrier-Grade NAT (CGNAT), outside devices cannot locate your computer's exact network endpoint.
A: In rare cases, your ISP may be actively blocking Parsec’s traffic. Try:
Locate in the list and ensure both Private and Public checkboxes are selected. Click OK . On macOS (Sequoia and newer): Open System Settings and navigate to Privacy & Security . Select Local Network . Toggle the switch next to Parsec to allow communication.
