the same way you debug stuff when you can't see the problem by just
staring at it: reduce it to a minimal error-case. So, remove some of
those /etc/sysconfig/iptables lines until it no longer fails, and
identify the exact line that causes the failure. Then stare at that one
line and understand why it's failing.
