Title: Fix iptables checking on RedHat

This is not working as it was envisioned it appears. It does not
correctly take into account all of the different ways you could set an
iptables rule, from --in-interface or -i, to whatever you want. It is
better to just use the built in iptables -C to check the chain for the
rule that it renders.

With this iptables-save stuff in place, it is currently giving me
duplicate rules for everything on RedHat distributions.
