You're most welcome.  The one problem with your reasoning regarding the
default policy of ACCEPT is that the last rule in the RH-Firewall-1-INPUT
chain is a 'drop all' rule...  Every RedHat/Fedora/CentOS box I've ever set
up nearly the first thing I do is delete the default firewall and construct
my own - I don't like the way they structure theirs.  IMHO best practice
(and clearest logic) is to enable a DROP policy on INPUT and FORWARD
chains, and add explicit ACCEPT rules for desired traffic.
