Some thoughts:

1. It could possibly be down to a reverse lookup of the IP. Have 
you got a working DNS ? Ensure the respective IP addresses 
are in the machines "/etc/hosts". For example, on both 
machines, make sure the file includes something like:

        192.168.0.5  hostservername
        192.168.0.6  hostclientname

2. What do the logs say ?

3. Since you actually do make a mount, this does not appear to be a 
security issue. However, it is always good to review "/etc/hosts.allow" 
and "/etc/hosts.deny". Check to ensure everything appears OK.

4. Check that portmap is running (on the client) 
before the mount. To be sure, execute (as root):

  /etc/init.d/portmap start

And to make it happen on bootup:

  rc-update add portmap default

5. Read the NFS HOWTO, particularly the security advice:

Sorry about the lack of list headers. My mail 
setup is currently less than ideal.
