I know that's an article of faith among networking people but it's not actually true.

I know that's an article of faith among networking people but it's not actually true.
- Dagger2 1mo agoIt is true. NAT only changes the source address used for outbound connections, it doesn't deny inbound ones. You don't need to take that on faith either -- you can just test it.
- tptacek 1mo agoGo ahead, make an inbound connection to my dev laptop. I'll even give you the IP address: it's 192.168.8.21.
- Dagger2 1mo agoGet me onto the network that's on the WAN interface of your router, disable the firewall on it, and I will. How do you want to go about doing this? Although, 100% of the time people have asked me to do this they chicken out at actually doing it, so I suppose you will too. You might prefer to test with some network namespaces instead.
