FreeBSD

To set a FreeBSD machine up as a NFS server, add the following lines to /etc/rc.conf 

mountd_enable="YES"
nfs_server_enable="YES"
rpcbind_enable="YES"
rpc_lockd_enable="YES"
rpc_statd_enable="YES"
mountd_flags="-r"

Since /storage is a single mount, you will need to define the same directories exactly the same for all the different permissions you want to define in /etc/exports. For example: 

/storage/downloads /storage/backups/esxi -ro -network 10.1.1.0 -mask 255.255.255.0
/storage/downloads /storage/backups/esxi -maproot=root -network 10.1.1.2 -mask 255.255.255.255

It would be invalid if the second line had only /storage/downloads as it will cause the first entry to be ignored by the parser.

To apply your changes, restart mountd. 

service mountd restart

showmount should show both exports: 

showmount -e
 Exports list on localhost:
 /storage/downloads                 10.1.1.0 10.1.1.2
 /storage/backups/esxi              10.1.1.0 10.1.1.2


Linux

Firewall

# firewall-cmd --permanent --add-service=nfs
# firewall-cmd --permanent --add-service=mountd
# firewall-cmd --permanent --add-service=rpc-bind
# firewall-cmd --reload

Troubleshooting

rpc.nfsd: writing fd to kernel failed: errno 111 (Connection refused)

You need to start rpc.bind 

/etc/init.d/rpcbind start
