Status in sync with DMZ core

Maintaining Status

Any Status updates in DMZ core will be propagated to the Central CORE.

Be selective on Bridge Rules – DMZ core should be relatively small as it would

need to transmit all worldview notification Source CORE not in the same server

as the Bridge Instance. Not best practice
