You should be able to find some information in your log files and possibily dmesg

My guess is you are missing some modules for iptables in your kernel.

Subject: [gentoo-server] Iptables Changes


After a recent kernel + iptables update I now find that iptables fails to
start with my saved rules. All it says is that the final COMMiT
line fails. Is there a way to troubleshoot this without typing each rule
by hand? Maybe some debug / verbose flag?
