Endpoint Detection Server in the DMZ

After installing an Endpoint Detection Server in the DMZ it shows as "Unknown" in the Enforce Console.
Using the standard port, 8100.
The Enforce Server can ping the Detection Server.
The Detection Server cannot resolve the Enforce Server's host name.
Adding the Enforce Server to the Detection Server's hosts file does not enable communications.

Cause

The firewall logs showed that the firewall was dropping the packets from the Detection Server to the Enforce Server.

Resolution

The firewall team modified the rule that was dropping the packets and now the Detection Server shows as "Running" in the Enforce console.
