Check your router setup: Log into your router and look for the WAN/Internet section. If it shows a local IP address (e.g., 192.168.x.x or 10.x.x.x), you might be double NATed. Run a traceroute: Open Command Prompt or Terminal and type `tracert` (Windows) or `traceroute` (Mac) followed by a common website. If you see two consecutive private IP addresses, you're likely double NATed.
