Front-end application for the powerful iptables Linux firewall.
Allows you to restrict which apps can access the network.
This is the perfect solution if you don’t have an unlimited data plan, or just wants to see your battery lasting longer.
For advanced users, it also allows you to manually define custom iptables rules.
Please remember to disable the firewall before uninstalling, otherwise you will need to reboot your device to turn it off.
This one is GOOD one guys, and if you’re a rooted user of an Android device, you should definetely give this one a try.

How To Root In Android

When you are on Limited Plan for net and you want save your data this app is going on.
The name of the app is DroidWall, and I can confidently say I will be keeping this firewall installed on my phone and tablet. DroidWall acts very much like a desktop firewall, and actually allows you to specify which apps can acces the internet, and which ones can’t, giving you way more control and protection of your device.
The app has a very simple dashboard control to allow you to determine how apps access the internet, allowing you to easily control apps that misuse their permissions. You can even toggle apps to allow internet access via wifi, but not with 3G cellular data and vice versa. After that, you simply activate the firewall and your good to go. Full control over apps and their permissions, with the ability to choose where they can and cannot access the internet from (3G or Wifi). I likey.
Remember though, some apps need and rely on internet access. So if you block your browsers internet access on wifi and 3G, you won’t be able to surf. Or if you choose to block an app that relies on in app advertising, you’re also blocking how the developer makes money. Just think carefully about what you want to block and what you don’t and you’ll be just fine.
I personally love this firewall. No more worrying about in app advertisers tracking my location or apps uploading personal data. No more worrying about what apps are doing when they access the net. This is the only firewall I have seen that I can honestly say should have been included with Android, and I don’t have any plans of uninstalling it anytime soon.
