Dhcpcd and iptables problems (BLFS 6.1)

I've solved the running twice issues, thanks.
I'm kinda dense about the kernel support. I think I've turned on the correct
options, but there quite a few sub-options. Iptables still complains loudly.
I'm reluctant to turn everything on.
Which items/subitems in
Networking ⇒ Networking Options ⇒ Network Packet Filtering ⇒ Core
Netfilter Configuration (and) IP: Netfilter Configuration
Are actually required to be ON ?

I might be wrong, but I think this is because the dhcpcd service doesn't
exit gracefully if it's already running. But, if you fix the configuration
to only run it once, everything should probably be fine.
