iptables mirror target for kernel version 2.6.36

December 6th 2010

During my last kernel upgrade I recognized that the iptables mirror target I published here, here and here does not work anymore with kernel version 2.6.36. You can download the newer version for 2.6.36 and probably future kernels here:

MIRROR.2.6.36.tar.gz (13499 downloads )

To build the module, boot the kernel you want to use the module with. Afterwards unpack the archive, run the compile.sh script and the install.sh script.

Now you may use the mirror target in place of the reject or drop target in the INPUT, FORWARD and PREROUTING chains, like this in your firewall script:

$IPTABLES -A INPUT -j MIRROR

Beware: The use of the mirror target may have strange results, i.e. if you want to connect to the iptables protected machine, you may end up connecting to the local machine without recognizing it. It also may use much bandwith. Worst case: if you have two machines using this module they may end up playing pingpong. So you have been warned, use with caution and at your own risk. For more information see: MIRROR target.

Downloads for older kernel versions are below. Notice the version numbering 2.6.25 works for kernels up to 2.6.27. 2.6.28 also works for 2.6.29 and 2.6.30 kernels. The 2.6.13 version of the module should work up to kernel version 2.6.16.

MIRROR.2.6.35.tar.gz (13455 downloads )
MIRROR.2.6.31 (13607 downloads )
MIRROR.2.6.28.tar.gz (13964 downloads )
MIRROR.2.6.25.tar.gz (13782 downloads )
MIRROR.2.6.24.tar.gz (14693 downloads )
MIRROR.2.6.13.tar.gz (14189 downloads )
