CHAPTER 6 Web-Based Management
➢
To log in to the Web interface using CAC:
1. Insert the Common Access Card into the card reader.
2. Enter the password only. As some browsers require that the username be provided, it's
recommended to enter the username with an arbitrary value.

Configuring Web and Telnet Access List

The Access List table lets you restrict access to the device's management interfaces (Web and
CLI) by specifying IP addresses (up to ten) of management clients that are permitted to access the
device. Access to the device's management interfaces from undefined IP addresses is denied. If
you don't specify any IP addresses, this security feature is inactive and the device can be
accessed from any IP address.
The following procedure describes how to configure the Access List through the Web interface. You
can also configure it through ini file [WebAccessList_x] or CLI (configure system > mgmt-
access-list).

➢
To add IP addresses to the Access List:
1. Open the Access List table (Setup menu > Administration tab > Web & CLI folder > Access
List).
2. In the 'Add an authorized IP address' field, configure an IP address, and then click Add New
Entry; the IP address is added to the table.
If you have configured IP addresses in the Access List and you no longer want to restrict access to
the management interface based on the Access List, delete all the IP addresses in the table, as
described in the following procedure.
When deleting all the IP addresses, make sure that you delete the IP address of the
computer from which you are currently logged into the device, last; otherwise, access
from your computer will be immediately denied.
➢
To delete an IP address from the Access List:
1. Select the Delete Row check box corresponding to the IP address that you want to delete.
2. Click Delete Selected Addresses.
Configure the IP address of the computer from which you are currently logged into
the device as the first authorized IP address in the Access List. If you configure
any other IP address, access from your computer will be immediately denied.
If you configure network firewall rules in the Firewall table (see
Rules), you must configure a firewall rule that permits traffic from IP addresses
configured in the Access List table.
