Employees enter their timesheets electronically and this information is transferred across the network to a database server in the accounting department. The client server application that handles this operates over TCP using port 2200. Accounting staff members that are located outside Las Vegas as well as system administrators need full access to all of the resources in the Las Vegas site. These users all reside on the 24 network in Tulsa. You decide to take this opportunity to control access to the router terminal lines as well in order
