getting iptables into embedded kernel

Yes, did that and then I try to run it but it only says "cannot execute binary file"
What machine were you using to compile the iptables binary?

You mentioned, your target machine is a PPC, if you compile iptables on an x86 machine without cross compiling option for PPC, you will end up with an Intel binary that will not run on Power-PC architecture.

I compile on a PC linux box, my target is a PPC 85xx. I use a denx distro.
First I thought this goes into the kernel and the KERNEL_DIR takes care of that.
I did have set my CROSS_COMPILE to my target and did set the PATH as well. I've just tried again with ARCH=ppc and CROSS_COMPILE=ppc_85xx- ;this doesn't work either.
