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

STATDOPTS="--port 32765 --outgoing-port 32766"

File /etc/default/nfs-kernel-server

RPCMOUNTDOPTS="-p 32767"

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.

options lockd nlm_udpport=32768 nlm_tcpport=32768
options nfs callback_tcpport=32764

It is possible to then open the following ports in the firewall.

UDP     111
TCP     111
UDP     2049
TCP     2049
UDP     32764:32768
TCP     32764:32768
