Example 3 - Single WAN Port Dedicated to Manager
In this example, a single WAN port (WAN 1) has been dedicated for exclusive use by a manager
workstation (IP address 192.168.2.4). This is done by restricting all other employee workstations to
either WAN 2 or WAN 3. The end result is that the manager workstation has exclusive access to
WAN 1 (meaning @ 50 Kbps bandwidth automatically), plus the benefit of added bandwidth if WANs
2 and 3 are available or have "spare" bandwidth.

Sales Employee Workstations
The configuration above shows two groups of workstations, each restricted to a specific WAN port.
The Marketing Employee Workstations are restricted to WAN 2, and the Sales Employee
Workstations are restricted to WAN 3. In order to do this, you need to set up the WAN ports such that
each user is restricted to either WAN 2 or WAN 3. This is done through the WAN Setup dialog box.
The dialog box below shows the WAN 2 tab. In this dialog, the IP addresses for the Marketing
workstations have been added to the Hosts restricted only to this port list. When any of these
workstations launch an application, the ProxyServer will restrict its use to the WAN 2 port.
