This is correct, almost all user side traffic is nat’d (masquerade/Src-nat) thus port knocking nor any ports externally being open, does not apply. (NAT , in general, = how the multiple devices at your home all share a single public IP address from your ISP) This article mainly addresses servers / public facing services (which do not make use of nat) |
