NAT is not a firewall. Full stop.

Many home routers are horrifically insecure with numerous remote vulnerabilities. Many IoT devices have vulnerable and accessible interfaces locally and externally.

I didn't mean to imply that a NAT was a firewall. Most home routers, which are for NAT (mostly) come with a firewall. Albeit a basic one, it still comes with one.

It reminds me the times when I was on phone with my ISP and he reboots my router remotely, live. In my head: what the * !?

Now, I'm paranoid each time they push an upgrade without warning. It was them or an E.T?

I always use another router after the one by the ISP, for precisely that reason.
