Re: [K12OSN] NAT and DHCP

There is nothing else to be running on this box.  It's purpose is a 
fileserver and DHCP/NAT.  May run terminal services but not at this time.

I tried to get NAT to work but when I
 service nat start

the network goes away.
then I stop it and the network comes back.

I'll keep poking at it. . .
