Yes I can help you, but not directly with the problem.

Even though you don't appear to be a native English speaker, you 
could try some basics - eg some capitalisation would make your posts 
easier to read.
But the main problem is you give so little information. Your problem 
description reads as "I did something rather vague and it doesn't 
work". There just isn't enough to go on.
I'd suggest you read this page :
http://www.catb.org/~esr/faqs/smart-questions.html

But on your specific query, the things that do come to mind are :
1) Do you have basic connectivity ? Ie, from the guest, can you ping 
the server and get a reply ?
2) Are there any firewalls or iptables rules in place ?

1) is the first one to tackle - if there isn't IP connectivity then 
nothing is going to work.
For 2), try completely clearing the firewall and see if that helps. I 
do know that NFS isn't a one step thing to enable in a firewall - you 
have to lock-down the ports it uses as it now defaults to using 
random ports and that would mean just opening everything up.
