Better yet, if you are running Fedora (or RedHat derived) run the
program 'lokkit' and select the box to allow NFS. Lokkit is a small
program to configure the firewall/iptables in Fedora.
If you find that you cannot mount your NFS share, and get a 'permission
denied' error, but that you can *then* get in, if you run 'iptables -F'
on the NFS server end of the pair, then your firewall is set to refuse
NFS access. Use lokkit.
You should NOT just turn of iptables: That IS your firewall!
