Hi,
We need a little help in setting up the network for our worker nodes. 
Currently our worker nodes are on an internal subnet which is not routed 
out.
But the LCG installation points out that a few outbound connections from 
the WN's should be enabled for the experimental software to run. I do not 
have previous experience with setting up NAT (which I believe should be 
sufficient here)

Our VO's are cms and dteam. So could someone please give the iptables 
configuration or point us to relevant docs?

Thanking you
Kashyap
