Lifer
What routers out there have L7 filtering and how do I know ?
Most firewalls I know also act as layer 3 devices. No need for a router in front of the firewall.
Pfsense and Sophos are free products that will accomplish L7 filtering while routing traffic.
True, unless you need wireless, then you are probably going to want to keep your router to use as a AP, pfsense doesnt do wireless well, or at least it didnt use to.
