Good evening from Singapore,

Is it possible to setup a Linux-based firewall with netfilter/iptables to 
perform *DEEP PACKET INSPECTION (DPI)* at OSI Layer 7?

Do existing open source firewalls like pfSense, OPNsense, IPFire, ClearOS, 
VyOS, Smoothwall, Untangle, NG Firewall, ufw, ConfigServer Security, IPCop, 
Shorewall, Endian Firewall Community, etc etc, support *DEEP PACKET INSPECTION* 
at OSI Layer 7?

I am using pfSense 2.4.4-p1 Community (virtual appliance) at home, which 
appears to be the best or top open source firewall in the world at the moment.

Thank you very much for your advice.
