Configuring the Web and Telnet Access List
Use this screen to define up to ten IP addresses that are permitted to access the gateway’s
Web and Telnet interfaces. Access from an undefined IP address is denied. This security
feature is inactive (the gateway can be accessed from any IP address) when the table is
empty.
To manage the Web & Telnet access list:
1 Open the ‘Web & Telnet Access List’ screen ( Advanced Configuration menu >
Network Settings > Web & Telnet Access List option); the ‘Web & Telnet Access List’
screen is displayed.
Figure 59 Web & Telnet Access List Screen
2 To add a new authorized IP address, in the ‘New Authorized IP Address’ field, enter the
required IP address (see the note below) and click the button
Add New Address ; the IP
address you entered is added as a new entry to the Web & Telnet Access List table.
3
To delete authorized IP addresses, check the Delete Row checkbox in the rows of the IP
addresses you want to delete (see the note below) and click the button
Delete Selected
Addresses ; the IP addresses are removed from the table and can no longer access the
Web & Telnet interfaces.
4 To save the changes so they are available after a power fail, see Save Configuration .
The first authorized IP address you add must be your own terminal's IP address. If
it isn’t, further access from your terminal is denied.
Delete your terminal's IP address from the Web & Telnet Access List last. If it is
deleted before the last, access from your terminal is denied from the point of its
deletion on.
