NFS on FC5

[Margaret_Doll]

On a new FC 5 system, I am trying to serve up five large partitions 
(all over 80 Gb apiece) across the network.  In particular to an FC2 
system.

The new system can mount partitions from other systems on the network.

I have disabled selinux.  I have the correct hosts in /etc/host.allow 
with permissions to all.

On the client I keep getting that there is no route to the host.  
Although from the client I can see the services on the server.

[root at client  root]# rpcinfo -p server

     100005    3   tcp    653  mountd

[root at client root]# mount -v /dist
mount to NFS server 'server' failed.
RPC Error: 12 ( Remote system error )
System Error: 113 (No route to host)

The line from /etc/fstab on the client is

server:/numbers1   /dist                   nfs4    proto=tcp,soft,bg,rw

I have tried this line with "nfs" instead of "nfs4"  and without the 
"proto=tcp" option.

What is going wrong?
