Given the above, I'll assume that nfs is running (for now)...The responses seem to indicate nfs is working but I know very little about managing nfs.

Do you have any entries in "/etc/hosts.allow" or "/etc/hosts.deny"? I don't think so but I do have entries in /etc/hosts and well as /etc/samba/smb.conf.  I checked and there are no entries in /etc/hosts.allow or /etc/hosts.deny.

Do you have iptables running without allowing loopback access?  As far as I know I don't have iptables running at all. I checked using ps -A | grep "ip" and there is nothing with "ip" in it.

Awaiting you response.  I am getting close to the time I have to put 
cic2ext (192.168.1.15) back into production mode.
