Are you running nmap from the Redhat box that you are trying to connect to? The reason I ask is that if you are, often it will show ports as open that are not actually open to outside machines because of iptables. What you might try is stopping iptables with service iptables stop and see if you can connect. If you can, then you need to tweak iptables using the redhat-config-securitylevel and set it to allow incoming ssh.
