you also need to add portmapper ( port 110 ) and lock the following ports preventing portmapper to assign random ports
Uncomment the following in /etc/sysconfig/nfs and make sure the portmapper is restarted.
RQUOTAD_PORT=875
LOCKD_TCPPORT=32803
LOCKD_UDPPORT=32769
MOUNTD_PORT=892
STATD_PORT=662
Choose ports as you like and add them in the firewall.

Below is my firewall rules for iptables.
everything is working fine except for NFS
I cannot mount my drive.
If I turn off iptables I can mount.
Looking at this : http://www.centos.org/docs/5/html/Deployment_Guide-en-US/ch-nfs.html
Important
In order for NFS to work with a default installation of Red Hat Enterprise Linux with a firewall enabled, IPTables with the default TCP port 2049 must be configured. Without proper IPTables configuration, NFS does not function properly.
The NFS initialization script and rpc.nfsd process now allow binding to any specified port during system start up. However, this can be error prone if the port is unavailable or conflicts with another daemon.
I have port 2049 listed in my iptables.
Is there a reason I cannot mount?
thanks,
Jerry
