Error applying iptables rules. Exit code:2

```
Motorola xt300 rooted, Firmware 2.1-update1; Base band A309_U3_01.72.0; kernel
2.6.29 wmm125@zbr05Inxdroid07 #2; version number SESLA_U3_01.72.0; i turn on
the firewall and this appears:

"Error applying iptables rules. Exit code:2

iptables v1.4.10
iptables v1.4.0: can't initialize iptables table 'filter':Table does not exist
(do you need to insmod?) Perhaps iptables or your kernel needs to be upgraded."

I think the app may not run on this kernel.

Start by reproducing the failure on the Motorola XT300 configuration described in the report and inspect the iptables and kernel support involved. The issue is done when the firewall rules apply without exit code 2, or the device/kernel incompatibility is clearly documented.
