If you're able to configure firewall rules, you're well outside of any normal users able to make up a significant amount of P2P traffic. And to most users, port forwarding and configuring a firewall rule are nearly identical. Truth is that for most users, NAT today is almost always synonymous with a firewall that has deny in, allow out policy. 10+ years ago, a lot of folks often connected their machines to the Internet in the way you specified. You could go around scanning people's systems, viewing their fileshares and so on. NAT "fixed" a lot of that. |
