===== Defining NFS ports to be ports based firewall friendly =====

It's easy to configure the port options for the **statd** and **mountd** RPC services, thanks to the use of ''/etc/default/*'' by the init-scripts.

File ''/etc/default/nfs-common''
<code>STATDOPTS="--port 32765 --outgoing-port 32766"</code>

File ''/etc/default/nfs-kernel-server''
<code>RPCMOUNTDOPTS="-p 32767"</code>

The NFS daemon (**rpc.nfsd** or just **nfsd**) will listen on port 2049 by default if no port is specified.

Create a ''/etc/modprobe.d/nfs-local.conf'' file to provide the lockd module with options.
<code>options lockd nlm_udpport=32768 nlm_tcpport=32768
options nfs callback_tcpport=32764</code>

It is possible to then open the following ports in the firewall.
<code>UDP     111
TCP     111
UDP     2049
TCP     2049
UDP     32764:32768
TCP     32764:32768</code>
