Hi PH! I'm Sally, maker of 17NAS 👋 I run a home lab and constantly needed to answer questions like "is my NAT symmetric?", "do I actually have working IPv6?", "am I behind CGNAT?" — existing tools each covered one piece, so I built 17NAS to put them together: NAT type test, IPv6 connectivity with latency comparison, CGNAT detection, all in the browser with no signup. There's also a curl API (v4.17nas.com / v6.17nas.com) with JSON output that I use in my own monitoring scripts. It's free, no account. Would love your feedback — especially edge cases where the detection gets it wrong!
