[K12OSN] NAT and connections through it.

These are not thin clients. . .
It is a lab of computers. An E.A.S.T. lab to be specific, so they pretty much have full reign over them. I put the NAT in there so that when they get virus innfected, I can shell into the server that runs NAT and stop NAT and they are isolated. . . jsut that fast.

Now, I need to be able to let them talk to a virus server out on the rest of the network for updates and etc. . .

Thanks for the reply!

Are the computers in the lab thin clients? If they are your shouldn't  
even need NAT.

If they aren't, the NAT service should allow connections to be  
established from the lab to computers outside the lab. If you want  
computers outside the lab to initiate a connection, you need to  
manually forward addresses.
