Debugging NAT problems in the kernel level

Dear developers,

I've posted before about the NAT or ip_conntrack problem that I have with
kernel 2.4.17_mvl21-malta-mips which was modified by other vendors as well
on it's way to me and it is suffering from a *serious* networking issue where
NAT is not working in the kernel level.

I need help with tools and knowledge on how to debug, diagnose and figure
out what exactly is the problem and where is it coming from.
If required, I'll be happy to provide access to the kernel sources that I have
for further reviewing or posting just the relevant parts here.

I've given it a go myself and I need a guiding hand.
I will appreciate any post and comment on this subject.
