>I believe you've forgotten to build support for NAT in your kernel:
Nope that's not it

grep IP_NF_IPTABLES .config

CONFIG_IP_NF_IPTABLES=m

And it's not that I can't insert anything in the chain. It's --dport
that gets me the error message. I played around and started with inserting
a blank rule.
