Example 4 – Multiple Subnets, Multiple Local Services In this example, there are two separate locations. The following is a list of assumptions that are made regarding this particular example: • The locations are spread apart and have only a minimal connection to each other • There is a network administrator at each location who is responsible for looking after Deep Freeze at that location • Both locations need to be administered from a third location In this example, the Remote Consoles are set up at each location and a local service is used: • Location 1 (a computer lab on campus) uses port A to communicate with the clients and the connections hosted by the Console. The school library’s computers use port B. The Console in the technical support department uses the connections hosted by both lab and library Consoles. • Any console not directly communicating with a computer should have the local service turned off. The following diagram shows the network topology: The benefit of this setup is that it allows all the packets sent from the clients in Location 1 to be contained at that location. The less distance a packet must travel, the less chance there is of the packet failing. The administrator in the lab can connect to the local service in the same location 1 but cannot connect to the local service in the library. The reason for this is that the lab administrator does not know the password to access the local service for the library. The same goes for the administrator in the library. If technical support knows the password to both local services (lab and library) the local service at both locations can be connected to, in order to administer all the clients.
