With DSM-5.1 it's already there.

cd /usr/syno/etc/rc.sysv
cd /usr/syno/etc/rc.d
mv S83nfsd.sh.sample S83****.sh
mv S83nfsd.sh.sample S83****.sh
reboot (or /usr/syno/etc/rc.d/S83****.sh start)

Note, in newer versions (DSM4), the <code>/usr/syno/etc/rc.d/S83nfsd.sh</code> will already exist. If you try to "<code>start</code>" it, you will get a message telling you that "<code>NFS server is not enabled. Skip...</code>"
You'll need to edit the <code>/etc/synoinfo.conf</code> file and add <code>runnfs="yes"</code>.  Then you'll be able to run <code>/usr/syno/etc/rc.d/S83nfsd.sh start</code>

In the exports file, add the following line

Save the export file
 
Check if the file /var/lib/nfs/rmtab does exist, if not, then run the following command

'''Important:''' NFS on the Synology Server is case-'''insensitive''' (as of November 8, 2008; [http://www.synology.com/enu/forum/viewtopic.php?f=3&p=45501 this may change in a later firmware version]).  This means if you perform backups by (say) [http://www.samba.org/rsync rsync], and the source directory contains files named "Foo" and "foo", the destination directory will contain only '''one''' of these files, as "Foo" ovewrites "foo" case-insensitively. This behavior happens silently.
'''Update: DSM is case-sensitive over NFS since DSM 2.1'''

== MTU Jumbo frames ==
==Further Reading==
For some NFS clients (eg. TViX 6500/7000), errors are reported if jumbo frames are enabled. Mounting the NFS is possible: try disabling the jumbo frames setting in the Synology Disk Station Manager -> system -> network.
