A couple of things are likely. I imagine you either set the firewall option during installation (master) or you took the default which is Medium. Therefore you maybe blocking most of the traffic you desire. Even if not, you didn't specify what type of connection you're trying to make. Try ssh first. RH turns it on by default. If you can ssh to the master from a slave then you likely just have too strick of a fw setting. If you want telnet, ftp, etc. then you should goto /etc/xinetd.d/ and vi each appropriate file and turn them on by setting the disable=yes to disable=no. Then restart xinetd and you should be cool.
