Continuing the discussion from Nethserver BDC and packet monitor:

NethServer Version: 7.3
Module: firewall

Is there any way to monitor packets blocked by the firewall / proxy by web console (only those blocked)?

I use logwatch. One of the sections it produces every night is this:

--------------------- iptables firewall Begin ------------------------
