> what most people are confusing with firewalling is actually NAPT
Yes. I should be clearer myself as just referring to NAT this way could serve to increase the confusion.
What most people just call NAT, what is offered by simple home/office routers (or APs when not in bridge mode or similar) and phones in tethered wireless mode, is actually NAPT (Network Address Port Translation), which is a subset of SNAT (Source Network Address Translation), which is in turn a subset of NAT.
