Are IPtables inbuilt in android kernel? If they are, how to use them in our android application?
Answer
- iptables is available in Android source distribution. That version however only works with devices built with Linux kernel 2.6.29.
- Users of retail Android devices cannot access iptables binary. Even Android OS itself cannot access that binary. This is hard-coded in Android. Many devices also don't have iptables at all.
- The only way to access iptables binary is to build your own Android images. Check out http://randomizedsort.blogspot.com/2010/08/building-android-and-linux-kernel-for.html.
