Hello, :)
In the pass, i use pfsense, and i would try opnsense, actualy on virtual machine. Sorry for my bad english.
1)
Whit a fresh install, LAN Rules:
Rules direction: in:
Interface LAN / Protocol IPv4 / Source: LanIP / Port any / Destination any / Port: 53,80,443 / Gateway any / Description:lan in
I see some Label "let out anything from firewall host itself", its a normal message? (we can ignore them?) I dont find many information on internet.

2)
Sometime i get "Default deny / state violation rule" (=no match rule found) and i couldn't find why (Dest. on port 443 was allow in my LAN rules). Actully i reload a backup and i dont be eable to repoduc that. ???

The direction "in" in the LAN interface mean "packet from Lan computer to LAN interface"
and "out" mean "packet from LAN interface to Lan computer"
same from the WAN. I am right?
This is little ambiguities. Its can make doubt with packet IN and OUT the wan.
Best regard 2023. :D
