Change fixed ports for nfs the hard way.

rpc.statd

[root@anden ~]# diff /etc/init.d/nfslock{,.bak}
80c80
<       daemon rpc.statd -p 4000 "$STATDARG"
---
>       daemon rpc.statd "$STATDARG"

rpc.lockd

/etc/modules.conf
options lockd nlm_udpport=4001 nlm_tcpport=4001

rpc.mountd

[root@redhat-strait ~]# cat /etc/sysconfig/nfs
MOUNTD_PORT=4002

rpc.rquota

/etc/services
rquotad         4003/tcp                        # quota
rquotad         4003/udp                        # quota

Daemon Name

portmap		111		iptables -A block -p udp -m udp --dport 111 -j ACCEPT
rpc.statd	4000		iptables -A block -p udp -m udp --dport 111 -j ACCEPT
rpc.nfsd	2049		iptables -A block -p udp -m udp --dport 2049 -j ACCEPT
      				iptables -A block -p tcp -m tcp --dport 2049 -j ACCEPT
rpc.lockd	4001		iptables -A block -p udp -m udp --dport 4001 -j ACCEPT

iptables -A block -p tcp -m tcp --dport 4001 -j ACCEPT

rpc.mountd	4002		iptables -A block -p udp -m udp --dport 4002 -j ACCEPT
				iptables -A block -p tcp -m tcp --dport 4002 -j ACCEPT
rpc.rquotad	4003		iptables -A block -p udp -m udp --dport 4003 -j ACCEPT

iptables -A block -p tcp -m tcp --dport 4003 -j ACCEPT

Change fixed ports for nfs the easy way.

If /etc/sysconfig/nfs is supported use the following config file.

#
# Define which protocol versions mountd
# will advertise. The values are "no" or "yes"
# with yes being the default
#MOUNTD_NFS_V1="no"
#MOUNTD_NFS_V2="no"
#MOUNTD_NFS_V3="no"
#
#
# Path to remote quota server. See rquotad(8)

# Port rquotad should listen on.

#Optinal options passed to rquotad
#RPCRQUOTADOPTS=""

#
# TCP port rpc.lockd should listen on.

# is random
#STATD_OUTGOING_PORT=2020
# Specify callout program
