Hmm, what module are you missing that prevents iptables + ipchains from working?
Ummm, the iptables/ipchains module?
I also don't have any userland iptables/ipchains commands in /sbin.
I say this, because, the codesourcery cross-toolchain is the only stable method for compiling kernels and kernel modules for the ls pro/live. Everything else can be compiled natively.
Also, in the upcoming weeks, a new kernel will be released, accompanied by a revised + updated native toolchain. Native compiles of the kernel + modules should not be a problem then.
Will this include a ipchains/iptables either as a module or natively? If so, I should probably just shut up and wait. Building kernel stuff for the preinstalled kernel seems like it is going to be much pain.
