I also agree the problem could be that you have not recompiled the
userspace utils, but it's strage, because I think p-o-m use to ask
for the iptables sources to be executed. Maybe you have a too old
version of iptables or maybe the p-o-m ng it's too new for your
quite old (2.4.20) kernel. Why don't updating the iptables to the
last version and also the kernel to 2.4.27 so you have to recompile
both of them?

The only people for me are the mad ones -- the ones who are mad to live,
mad to talk, mad to be saved, desirous of everything at the same time,
the ones who never yawn or say a commonplace thing, but burn, burn, burn
like fabulous yellow Roman candles.
