To tell if you have double NAT, follow these steps: Check your IP address on your router’s status page. If the WAN IP starts with 192, 172, or 10, you’re likely behind a NAT. Now, compare this to your public IP address by searching 'What is my IP' on a search engine. If the two IPs are different, you may have a double NAT issue. Double NAT can cause connectivity issues, so consider putting one router in bridge mode or using a single router.
