If there's a router between the user and the internet, then it's probably a moot point. Most routers have a firewall built in and locked tight by default.

Yeah, pretty much every residential broadband router uses NAT/PAT today out of necessity - the need to conserve of IPv4 address space leads ISP's to hand out 1 address at a time. The inherent advantage of using strict NAT/PAT outbound is that inbound connections of any kind (unless the user configures otherwise) are simply dropped outright.

Now you're on my turf - I'm an MPLS engineer.
