NFS ports are assigned dynamically. You have to set them to static numbers in
/etc/sysconfig/nfs
in order to open those ports (the ones that you are using) with iptables
LOCKD_TCPPORT=
LOCKD_UDPPORT=
MOUNTD_PORT=
RQUOTAD_PORT=
STATD_PORT=
STATD_OUTGOING_PORT=
and then open the ports that you set there as well as 111 (portmapper)
and 2049 (nfsd)
