Nethserver as BDC?

NethServer Version: 7.3

I’m using Nethserver 7.3 and I’m enjoying the experience. It is no doubt about small and medium-sized businesses.
But I have some doubts: can Nethserver 7.3 be used as controller backup domains?

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

Sorry my bad english, I used a translator
Best regards

What do you mean? Can you give us more details? BDC is an old term, 7.3 is and Active Directory.
What do you need?

I split your topic into two.
