As John R Pierce mentioned one of your first rule in the chain is 
"RH-Firewall-1-INPUT  all  --  anywhere             anywhere", this
simply mean everything with "DROP" after it will be ignored. iptables
will work its way down the chain, therefore you have to options
1. remove that line or 
2. move it at the bottom of the chain.
