Ports to open for NFS on Firewall

I have not set static port for statd,  lockd and mountd. Please let me know which port should I open at Firewall level for this Server for NFS client to connect . Below is O/P from rpcinfo. my os version is 11.11

Re: Ports to open for NFS on Firewall

As you haven't set static ports for statd, lockd and mountd, you would have to open ports 111 (rpcbind/portmapper), 2049 (nfsd), and the whole dynamic port number range 49152 - 65535 (for statd, lockd and mountd, because their port numbers might change on reboot and/or nfs daemon restart).

 

It would be better to make sure that you have the patch PHNE_34662 (or a newer patch that supersedes that one) installed, and specify static ports for statd, lockd and mountd. Once the required patch is installed, this is as simple as adding three lines to /etc/rc.config.d/nfsconf:

LOCKD_PORT=4045 
STATD_PORT=4046
MOUNTD_PORT=4047

After adding those lines, you'll need to restart the NFS daemons or reboot the system.

 

When static ports are set, you would only need a total of five ports for NFS:

  • 111 (rpcbind/portmapper)
  • 2049 (nfsd)
  • 4045 (lockd)
  • 4046 (statd)
  • 4047 (mountd)
