Introduction

If you need to use NFS through any security boundary then you will need to know the ports for NFSv3 to add to your ACLs or firewall rule sets.

Protocol

NFS uses TCP and UDP

Ports

The standard ports are as follows:

RPC = 111
NFS = 2049

The non standard ports are:

LOCKD = ?
STATUS = ?
MOUNTD = ?

These are the ports that need to be ascertained what is in use. Could be random high ports or could be locked to 4045, 4046, 4047. They could be anything. Until this is known it will not work.
