Show the answer and explanation

✓ Correct answer

  • Local 10.22.0.0/24 and remote 10.11.0.0/24.

Each side calls its own protected network local. The peer reverses local and remote perspective. Broad/public-only definitions are not the specified pair, and IKE/NAT-T ports are not the subnet addresses in this example.
