I have a NW 6.5 server with BM 3.8. Outside the BM firewall is a dmz
which has another firewall that is the portal to the internet. I have
added a third NIC to the BM server and intend to add a dmz for a NW6.5
server that will handle smtp traffic from internet and provide web
access. It will forward requests groupwise server in lan. The new dmz
is required because nw servers can't talk across a nat enabled
interface. My question is what are the packets that must be allowed
across the interface for a nw server to talk normally to the other
servers in the tree?
