What is the function of Shield-up in the taskbar icon (firewall applet)?
firewalld is already enabled.
So, basically what I wanted to know is what is the difference between Shield-up and the default option (shield not up ?)
Best explained here
The TL:DR is
- shields-up - blocks all connection
- shields-down - allows connections defined in the zone
The default zone is public
where my personal preference - on public networks is drop
