This is a fork of the popular application Droidwall that uses iptables to limit data usage and add security to Android. Droidwall was originally created by developer Rodrigo Zechin Rosauro.
The app was discontinued and did not function correctly on Android 4.x. So I decided to fix it.
ROOT ACCESS IS REQUIRED
If you don't know what ROOT ACCESS is please read this: http://en.wikipedia.org/wiki/Android_rooting
Android Firewall has all of the capabilities of Droidwall. It supports Android 2.2 and greater.
A firewall on Android is a great tool when it comes to the tiered data plans carriers have moved to and that's not even talking about the added security a firewall brings.
If you install Android Firewall and find that the software does not work correctly please install BusyBox and a Terminal Emulator. Both applications can be found on the Play Store. Open the Terminal Emulator and type busybox route without the quotes. Please send an e-mail to me with the output from that command to help in my troubleshooting.
You can also post issues or requests on my Github. https://github.com/skullone/
Android Firewall is open source software under GPL v3.
