Comment on Do I really need a firewall for my server?
hedgehog@ttrpg.network 1 week agoAre you saying that NAT isn’t effectively a firewall or that a NAT firewall isn’t effectively a firewall?

NAT simply maps IPS across subnet boundaries in such a way that upstream routing tables don’t need updating.
If you use destination NAT forward rules to facilitate specific destination port access, you are using a firewall.
