This I have done, but I still get 'error: no route to host'.

/etc/exports contains:
#
/frodo/Fc5all 10.251.227.*(ro,no_root_squash,insecure)
/data 10.251.227.3(rw)

Checking nfs status:
# /sbin/service nfs status
rpc.mountd (pid 1757) is running...
nfsd (pid 1754 1753 1752 1751 1748 1746 1745 1744) is running...
rpc.rquotad (pid 1730) is running...

The /etc/hosts file is populated with the ip's hostnames and 
aliasses, and /etc/resolve.conf points to my isp's server 
address.

I am trying to share Fc5all to do a network install.
