Network Firewall not functioning properly

I installed the latest build, realizing that the one I had was two months old (3.14).
I was prompted to restart but the firewall was not there so I managed to reinstall the firewall again.

Now the diagnostic tells me that something is not functioning; however it could not fix it. What I am seeing here is that the ‘Network firewall’ is not functioning. My question is what is this type of firewall and how does it work?

Second I have a .xml log that was created by the firewall since the error was unable to be resolved.

Nevermind. A simple restart resolved it.
