An external NFS server will not "just work" on the client nodes unless you set up the head node as a gateway. Oscar does not currently do this, partially because there are many ways to do it and partially because not everyone needs it. Also, partially because no one has done it yet :)
Here is a howto which I have used to set up my dual nic head node to act as a gateway to the outside network. http://tldp.org/HOWTO/IP-Masquerade-HOWTO/ I think the head node should be able to mount the files, but I am not certain it will work neccesarily without the gateway setup either.
