There is basicaly only one way to do it: Install firewalls (or packet filters) in the different DMZs. It would look like (in good old ASCII art): | | Uplink to the Internet | Firewall | DMZ public | Firewall | | "Downlink" | DMZ private

On that segment are various servers. The servers need to talk to other servers outside the segment;uplinkits the internet, downlink the backend servers. Some of the servers need to be able to talk among them.^-- from here on it is not clear which servers are which servers areon whichlink they are.We want to control which server can talk to which other server (inthesegment), utilizing one of the firewalls (lets say the uplinkone).Can the group suggest ways to accomplish that? We thought aboutusingL2 switches with "private VLAN", L3 switches with ACL, butconstantlycome across problems doing the routing properly.
