Good afternoon, I have the virtual environment as you can see below, where I have network A and network B, and I needed that all traffic that passes through the Firewall coming from network A, be subject to some rules, for example blocking sites.
Is there a way for me on the "EST" router to mark the packets coming from the 10.1.1.0/24 network and when these packets reach the "Firewall" router be properly inspected.
Observations:
The "Tondela-Router" router bridges the two interfaces.
There is PPoE authentication on the "SchoolsMainRouter" router for the "Tondela-Router" router interface
Between the "SchoolsMainRouter" router and the Firewall, NAT is done, and a static route from SchoolsMainRouter to the Firewall is placed.
