Welcome to the AFWall+ Wiki!

AFWall+ is an Android open source firewall client, focused on making it easier to work with iptables. It keeps track of your mobile broadband usage and can block internet access to selected apps to avoid exceeding your data usage.

AFWall+ needs the following to run at his best:

  • The Android 4.x OS (ICS/API level 15, NDK 10) or a higher version.
  • Your device must be rooted.
  • BusyBox and IPtables (also included as binary in AFWall+ for Kernel/ROM's without it!)
  • The Kernel/ROM must have init.d support (for external custom script and data leakage fix)!
  • The Kernel must have NETFILTER/CONFIG_NETFILTER enabled (adb pull /proc/config.gz - Once you unzip it, you can search for e.g. NETFILTER). AFWall+ normally check's it automatically if your Kernel does have support for it or not.

Not working on

Since Android supports over 11k devices it's impossible for AFWall+ to work on all of them. The community (YOU) must help in this case with a quality bug report to possible add the missing thing to your version/device to get it working, besides this we not supporting special Android version like:


  • If you've not installed AFWall+ from the official stores like F-Droid or Google Play Store you may need to temporarily enable "Unknown sources" in your settings if that's disabled.
  • Make a current settings backup (optional) - it will be saved under /sdcard0/afwall/.
  • Download the latest release from Google Play Store, GitHub or F-Droid.
  • Delete any previous version of the AFWall+ app, an upgrade from an existent installation is also possible.
  • Delete/Restore any remnant application/setting(s) directory from /sdcard0/afwall/ or similar.
  • Install the latest available version.
  • Restore your settings backup.
