Chapter 4: Networks
Note: Use care when choosing a specific role rather than Authenticate. The Specific
Role option allows network transmission via MAC addresses, which is inherently less
secure than the Authenticate option.
The following figure shows an example of fixed IP address assignments on the Edit
Managed interface page.
Optional. Edit the Fixed IP address assignments by selecting one of the following

commands from the Row Management drop-down list:

To remove a fixed IP address assignment from the BSC database, you must clear the
MAC address, IP address, and Host name for that client before saving the
information.
Optional. Using the IP Range Assignments table, define role assignments for devices/

users that have been assigned static IP addresses as they connect to the BSC on the
managed interface. Enter a range of IP addresses using the From and To fields.
Click Save to save the settings to the BSC database.

You might be prompted to restart the BSC. We recommend that you do not restart the
BSC until you have completely finished configuring the BSC for use in your network.
Configuring One-to-one Network Address Translation
Standard NAT, as described in "Configuring One-to-one Network Address Translation"
on page 4-16, maps every IP address on the managed side to one address on the
protected side. However, in some cases you might want to map certain addresses on the
managed side to specific addresses on the protected side, rather than to a single
protected side address.
One-to-one NAT is typically used to manage devices such as wireless access points from
a management station on the protected side without the need to add static routes to the
LAN router table.
To set up one-to-one NAT, you need to provide the protected-to-managed side address
mappings as follows:
Click the Network tab in the BSC administrator console, and then the Managed tab.
