was instead assigned to a Public (DMZ) zone: All the Workstations would be able to reach the Servers, but the Servers would not be able to initiate communications to the Workstations. Then create 2 access rules, [LAN 1 > LAN 2 Allow All] and [LAN 2 > LAN 1 Allow All], and it will work just fine. Also make sure that the interface is configured for HTTP and SNMP so it can be managed from the DMZ by PCM+/NIM. Thanks.
