Isn't the firewall config you describe just essentially a software NAT?

- dsr_ 6y agoNo, not at all. NAT means Network (and port) Address Translation. If you don't change the contents of packets, it's not NAT.
- j1elo 6y ago> If you don't change the contents of packets, it's not NAT. Oh well, yes. I agree. I was thinking more from the point of view of the behavior it causes: essentially establishing some sort of look-up table to verify if an incoming packet corresponds to a previously outgoing one. Where, if the entry in that table gets deleted, the incoming packets suddenly start being rejected.
