Default Seeking iptables/netfilter supporting Kernel for the LG OPTIMUS L90 D415

I want a v3.4.x kernel for the LG OPTIMUS L90 (D415) that has iptables/netfilter built in. The phone image shown by this forum in the index looks most similar to my phone model, can anyone recommend a kernel?

With my Sprint Epic I would use a tool called Odin, is the method of flashing a kernel to this phone the same? Can anyone get me the instructions on how to do it properly?
