ACL: Block a Whole Subnet #1
A contractor network can reach a protected subnet that should remain isolated.
Cenário
Beacon Logistics is separating a newly connected contractor network from internal operations. The contractor hosts can currently reach systems in a protected subnet, but the router and other approved paths must continue working. Restrict the affected source network as intended and confirm that the boundary blocks the whole subnet rather than only one test host.
