This is most likely a firewall issue.  Open up ports 111 (TCP & UDP),
2049 (TCP & UDP), and 4002 (UDP) on both machines.  If you firewall
REJECTs these ports, remove those lines.

On the NFS server side, add this line to /etc/sysconfig/nfs:
MOUNTD_PORT=4002

Restart nfs and iptables, and verify that it works.  Also, update the
nfs-utils on both machines using up2date.
