How Blocking Works The app creates a firewall alias named android_app_blocked on first block action, and a single block rule targeting that alias. Blocking a device adds its IP to the alias; unblocking removes it. Changes are applied via the OPNsense REST API immediately. License OPNsense Manager is licensed under the MIT License.
