Client Access Control What Is It? All users in the internal/intranet network may use the Internet through a controlled environment. [. . . ] Once the Client Access Control is enabled, all clients must use their client name and password to log in. Once logged in, the Matrox iSwitch associates the IP address of the user's terminal with the clients name and password. The Clients Access Control manages the flow of packets from this address using the time of the day and the remaining threshold specific to that user. © Matrox Networks 1999 TechNote #1 - Client and Site Access Control Page 2 of 3 How Does It Work? With the Matrox iSwitch Client Access Control configuration feature, the administrator can permit either: Specific clients with specific day and time restrictions. Specific clients with no day and time restrictions, while other clients have such restrictions. All clients with no day and time restrictions. The Client Access Control uses a packet filtering scheme on the packets received from the internal network to assure users are forced to obey their client profile. For client access, the packet filter checks the source address of the received packets. What You Should Know Since the Client Access Control is based on IP source address of the packets received from the internal network, each client may only be logged in from one machine. If the client changes the machine and tries to log on from another machine, the first client is logged out automatically. This also means that if the IP address of the user's machine changes, that client is automatically logged out and will have to log in again. If any client is logged on, no other client will be able to log on from any other machine using the same client name and password. If the client wants to log in from another machine, they should log out from the machine from which they first logged in. For more secure and efficient access, there is an automatic log out mechanism that can be enabled or disabled. When enabled, the automatic log out checks the traffic received from the user's machine. If no packets are received during a specified amount of time, the client is automatically logged out. This feature is designed for users that leave their workstation, forgetting that they may be logged on at the time. Site Access Control What is it? All users in the internal/intranet network may use the Internet through a controlled environment. [. . . ] The administrator must make sure that all the sites in the site table are resolved, specially if the Matrox iSwitch is to deny the access to these sites. What You Should Know Validation of the sites listed in the site access table is a primary concern. These sites must be verified before allowing clients to access the Internet.
