INSTRUCTIONS
Click on the firewall and configure it to allow ONLY the following communication:

* The HR workstation should be restricted to communicate with the Financial server ONLY, over the default SCP port.
* The Admin workstation should ONLY be able to access the servers on the secure network over the default TFTP port.
The firewall will process the rules in a top-down manner in order as a first match. The port number must be typed in and only one port number can be entered per rule. Type ANY for all ports.
