> Set regex value in nfs.exports.allowed.hosts property.

> <property><name>nfs.exports.allowed.hosts</name><value>206.190.52.[26|23]
> {noformat}
> With this value, neither nor can mount nfs and act as nfs
client. In conclusion, no host can mount nfs with this regex value due to access denied error.
> {noformat}
> >$ sudo su - -c "mount -o soft,proto=tcp,vers=3,rsize=1048576,wsize=1048576,nolock /tmp/tmp_mnt" root
> mount.nfs: access denied by server while mounting
