My point exactly.
As for infection behind the router, that's why I made sure to be clear that I was speaking of firewalls, not antivirus. Antivirus is never redundant, and should always be used. Window firewall, however (or any other software-based firewall), can safely be turned off, if one is using a NAT-enabled router.
Most are, these days.
