      • Drop: Restrict a specific address from accessing a specific service or port of the PBX, and do NOT send any error notifications back to the sender.
      • Reject: Restrict a specific address from accessing a specific service or port of the PBX, and send error notifications back to the sender.
  3. In the Defense Object section, configure relevant settings of defense objects.
    • Object Type: Choose the type of the source traffic.
