Bug Reports

Please see the issues section to report any bugs, make feature requests, and to see the list of known issues. Before you report a bug, take a look here.

Limitations

  • A firewall cannot protect against attacks that are performed outside the operating point. For example, if there is a Point-to-Point connection to the Internet.
  • A firewall cannot prevent corporate data from being copied to a memory stick or HDD, and having these removed from the building.
  • AFWall+ does not scan for virus/malware that may exist in the files that pass through it, because it is a firewall and not an antivirus solution.

Compatibility

AFWall+ has been successfully tested with Android versions 4.x - 7.x. (ICS, JellyBean, KitKat, Lollipop, Marshmallow, Nougat) and is reported to work with most Android variants, including stock ROMs.

We do not recommend using AFWall+ in combination with any of the similar solutions because this could result in conflicts and potential data leaks (iptables could get overwritten).

Upgrading

  • Make a backup of the current version (e.g. using Titanium Backup).
  • Do not remove the current version (otherwise your settings might get reset).
  • Download the new version.
  • Install the new version over the previous version.
  • Done!

Permissions

AFWall+ asks for the following Android permissions:

  • RECEIVE_BOOT_COMPLETED: Autostart (Bootup) AFWall+ after the system finishes booting.
  • ACCESS_NETWORK_STATE: Allows AFWall+ to access information about networks (iptables).
  • WRITE_EXTERNAL_STORAGE: Allows AFWall+ to write to external storage for debug log and export iptables rules.
  • ACCESS_SUPERUSER: Standard to support Superuser/SuperSU (by Koushik/Chainfire).
  • INTERNET: NetworkInterface.getNetworkInterfaces() needs android.permission.INTERNET. This is just being used to get the IPv4 and IPv6 addresses/subnets for each interface, so the LAN address ranges can be determined. Nothing is actually trying to access the network. Also take a look at Stackoverflow.
  • ACCESS_WIFI_STATE: Used to detect the tether state.

Compile AFWall+

Prerequisites:

  • Android SDK in your $PATH (both platform-tools/ and tools/ directories)
  • Javac 1.7 (or higher) and a recent version of Apache ant in your $PATH
  • Git in your $PATH
  • Use the Android SDK Manager to install API 19 (or higher)

Quick start:

git clone git://github.com/ukanth/afwall
cd afwall
./gradlew clean assembleDebug

For complete instructions, please take a look at the Wiki's How To Compile AFWAll section.

Compiling Native Binaries

On the host side, you will need to install:

  • NDK r10, nominally under /opt/android-ndk-r10
  • Host-side gcc 4.7, make, etc. (Red Hat 'Development Tools' group or Debian build-essential)
  • autoconf, automake, and libtool

This command will build the Android binaries and copy them into res/raw/:

make -C external NDK=/opt/android-ndk-r10
