Setting	Value	Description
Number of servers	integer	Specify how many servers to create. Increase if NFS client responses are slow. Keep this less than or equal to the number of CPUs reported by `sysctl -n kern.smp.cpus` to limit CPU context switching.
Bind IP Addresses	drop down	Select IP addresses to listen to for NFS requests. Leave empty for NFS to listen to all available addresses.
Enable NFSv4	checkbox	Set to switch from NFSv3 to NFSv4.
NFSv3 ownership model for NFSv4	checkbox	Set when NFSv4 ACL support is needed without requiring the client and the server to sync users and groups.
Require Kerberos for NFSv4	checkbox	Set to force NFS shares to fail if the Kerberos ticket is unavailable.
Serve UDP NFS clients	checkbox	Set if NFS clients need to use the User Datagram Protocol (UDP).
Allow non-root mount	checkbox	Set only if required by the NFS client. Set to allow serving non-root mount requests.
Support >16 groups	checkbox	Set when a user is a member of more than 16 groups. This assumes group membership is configured correctly on the NFS server.
Log mountd(8) requests	checkbox	Set to log mountd syslog requests.
Log rpc.statd(8) and rpc.lockd(8)	checkbox	Set to log rpc.statd and rpc.lockd syslog requests.
mountd(8) bind port	integer	Enter a number to bind mountd only to that port.
rpc.statd(8) bind port integer	Enter a number to bind rpc.statd only to that port.
rpc.lockd(8) bind port	integer	Enter a number to bind rpc.lockd only to that port.

Unless a specific setting is needed, it is recommended to use the default settings for the NFS service.
