NFS howto with static ports

First I'm going to edit the /etc/sysconfig/nfs to specify the ports I want to run on.

STATD_PORT=4000
STATD_OUTGOING_PORT=4004

LOCKD_TCPPORT=4001
LOCKD_UDPPORT=4001
MOUNTD_PORT=4002

Next I want to edit the /etc/hosts.allow to only allow specific hosts to access the resource.

nfs:192.168.1.

Finally lets allow some stuff to come in through our IP tables rules at /etc/sysconfig/iptables
