Dear CentOS community,
I have install centos via CD, DVD and Directly off the net via http and FTP. Now I want to do a NFS install from a local server and a client. Both, client and server are in the same vlan 

The server has a static address and the client gets its own address via DHCP. I download the DVD image from one of the mirrors and placed it under /centos-media/centosdvd32/DVD/CentOS-5.5-i386-bin-DVD.iso which is a dedicated partition on the server to hold all images. After that I exported the usual entries under /etc/exports and reloaded NFS using /sbin/service nfs reload. This is what my exports file looks like:

[root at zeus DVD]# cat /etc/exports

After doing so, I also modified the entries under IPtables to allow traffic in 111 and 2049 at the UDP/TCP level and restarted the service as shown bellow.

[root at zeus DVD]# cat /etc/sysconfig/iptables
# Firewall configuration written by system-config-securitylevel
# Manual customization of this file is not recommended.
:RH-Firewall-1-INPUT - [0:0]
-A INPUT -j RH-Firewall-1-INPUT
-A FORWARD -j RH-Firewall-1-INPUT
-A RH-Firewall-1-INPUT -i lo -j ACCEPT
-A RH-Firewall-1-INPUT -p icmp --icmp-type any -j ACCEPT
-A RH-Firewall-1-INPUT -p 50 -j ACCEPT
-A RH-Firewall-1-INPUT -p 51 -j ACCEPT

-A RH-Firewall-1-INPUT -s -m state --state NEW -p tcp --dport 111 -j ACCEPT
-A RH-Firewall-1-INPUT -s -m state --state NEW -p udp --dport 2049 -j ACCEPT
-A RH-Firewall-1-INPUT -s -m state --state NEW -p udp --dport 111 -j ACCEPT

[root at zeus DVD]# /sbin/service iptables restart

When I try loading the net-install disc from the client i get to the area where I specify the Ip of the server and the NFS path in the server, hitting enter returns "That directory does not seem to contain CentOS installation tree", I triple check the ISO and I know its there with all appropriate permissions. Can someone tell me what am I missing? I have spend all day trying to get NFS working in the local vlan, i know that all ports are open within the vlan at the routers level. Any clues?
