Chapter 52 System The following table describes the labels in this screen. Table 279 Configuration > System > FTP LABEL Enable TLS required DESCRIPTION Select the check box to allow or disallow the computer with the IP address that matches the IP address(es) in the Service Control table to access the ISG50 using this service. Select the check box to use FTP over TLS (Transport Layer Security) to encrypt communication. Server Port Server Certificate Service Control Add Edit Remove Move # This implements TLS as a security mechanism to secure FTP clients and/or servers. You may change the server port number for a service if needed, however you must use the same port number in order to use that service for remote management. Select the certificate whose corresponding private key is to be used to identify the ISG50 for FTP connections. You must have certificates already configured in the My Certificates screen (Click My Certificates and see Chapter 50 on page 643 for details). This specifies from which computers you can access which ISG50 zones. Click this to create a new entry. Select an entry and click Add to create a new entry after the selected entry. Refer to Table 275 on page 683 for details on the screen that opens. Double-click an entry or select it and click Edit to be able to modify the entry's settings. To remove an entry, select it and click Remove. The ISG50 confirms you want to remove it before doing so. Note that subsequent entries move up by one when you take this action. To change an entry's position in the numbered list, select the method and click Move to display a field to type a number for where you want to put it and press [ENTER] to move the rule to the number that you typed. This the index number of the service control rule. Zone Address Action Apply Reset The entry with a hyphen (-) instead of a number is the ISG50's (non-configurable) default policy. The ISG50 applies this to traffic that does not match any other configured rule. It is not an editable rule. To apply other behavior, configure a rule that traffic will match so the ISG50 will not have to use the default policy. This is the zone on the ISG50 the user is allowed or denied to access. This is the object name of the IP address(es) with which the computer is allowed or denied to access. This displays whether the computer with the IP address specified above can access the ISG50 zone(s) configured in the Zone field (Accept) or not (Deny). Click Apply to save your changes back to the ISG50. Click Reset to return the screen to its last-saved settings. 52.11 SNMP Simple Network Management Protocol is a protocol used for exchanging management information between network devices. Your ISG50 supports SNMP agent functionality, which allows a manager station to manage and monitor the ISG50 through the network. The ISG50 supports SNMP version 700 ISG50 User's Guide
