Can someone explain to me why NAT is not enough for security? (lemmy.world)

Networking noob here. I want to prevent all incoming requests except through a specific port, and that traffic is forwarded to a specific device on the network. NAT seems to do that just fine, it's almost like a kind of firewall by itself. What kind of threats are there that requires more than just NAT for security?
