I use NoPorts to access my Windows PC from my Mac ( my home internet runs on Starlink ) which uses CGNAT, making traditional remote access solutions basically impossible.
I tried Tailscale first, which is a great product, but it introduced too much latency. NoPorts just fixed the latency issue for me.
It genuinely solves a real infrastructure problem that affects anyone on behind a strict CGNAT. For a regular person with no networking background, the fact that it "just connects" despite all these constraints feels like magic.
