I have a security issue on the cluster i'm building. it's not yet in
production but i already can see the problem.

I use LVS-NAT on a 4 nodes cluster.

3 nodes are real servers and director in the same time.
1 node has an NFS share.

N1 N2 N3
  MGM

So, using LVS-NAT, i got forwarding activated meaning someone could
spoof the ip of my nodes and so, get access to the nfs share, which i
really don't want.
Any idea toget over this ?

Thanks :)
Pierre.
