Niki,
nfs v2 and v3 are fairly simple, however I have not yet managed v4 as it 
seem to need kerberos and individual user authentication rather than 
machine authentication as do v2 & v3.
If you use a firewall on your server, you will need to set up permanent 
ports for the various services that nfs uses. check out /etc/sysconfig/nfs
rpcinfo -p will show you what is running and what version and ports - 
very useful!!
