AFWall Boot AntiLeak
AFWall+ is the best firewall for people who want to keep a close eye on their device’s network traffic. But there is a small but important security hole in the normal Android boot process. This module is designed to fill that security hole, so your device is safe from the moment it turns on.
AFWall+ usually only uses its advanced “iptables” ruleset after the app has started. The problem is that the Android operating system can connect to the internet before AFWall+ is fully loaded and running. This opens up a short window of time during which apps might be able to send data without any restrictions, going around the firewall rules you set up so carefully. This module effectively shuts that window by blocking all internet access during the first boot sequence. This keeps the system safe and locked down until AFWall+ is ready to take over.
Core Operational Requirements
It’s important to know that this module isn’t a separate firewall. It is a companion tool that was made to work with AFWall+ and make it better.
- You must install AFWall+: You need to have AFWall+ set up and working correctly on your device. The only thing this module does is put a temporary network block on the whole system. It depends on the AFWall+ app to eventually remove this block and put your own rules into action. If you install this module without AFWall+, your device will not be able to connect to the internet until you remove the module.
Development Milestones and Version History
The module has changed over time with a number of updates to make it work better and work with more devices and Android versions.
v.1.0: Initial Release This first version added the main features and set up the basic way to block network traffic during the early stages of the boot sequence to stop data leaks before AFWall+ could start up.
v.1.1: Enforced Comprehensive Lockdown This update made the first block stronger by making sure that the traffic rules were followed on both the Wi-Fi and Mobile Data interfaces. This improvement makes sure that no data can leak, no matter what type of primary connection is active when the device starts up.
v.1.2: Improved Synchronization and Automation This version added important improvements to usability. There was a planned delay before network access was restored, which gave AFWall+ plenty of time to load all of its rules. The module also added an automated cleanup mechanism that deletes the temporary “afwallstart” script after it runs, making the system cleaner and more efficient.
v.1.3: Modern Android Compatibility Refinements This release improved the script cleanup process even more in response to user feedback and changes to the architecture in newer versions of Android. To make sure that it works on modern devices, the automatic deletion of the
afwallstartscript now checks both the/data/adb/post-fs-data.d/directory and the/data/adb/system.d/path. This makes sure that it works smoothly, especially for users of Android 11 and newer.
