Did pfsense have security-level value in each interfaces ?

As you know, most firewall have security-level at every interface ，Like outside 0, inside 100, DMZ 50 , it is used for high security level zones to access low security level zones.

No, pfSense does not have security zones or whatever you're talking about. You can fully control the traffic between interfaces, so you have more flexibility than simply assigning zones.

Not sure is the good Docktor is serious, but this is Cisco PIX/ASA speak. Lower numbers cannot initiate traffic to higher numbered zones. A fallback for those who are not good at crafting their rules, and I've seen plenty of ASAs with very poorly crafted rulesets…

No it doesn't, you may gently shoot yourself in the foot if you like to. Your decision. Or cabability.
