Chapter 45 Managing Firewall Devices
Configuring Firewall Device Interfaces
Step 1 In the Advanced Interface Settings dialog box, choose the option that identifies how you want this device
to handle Traffic between interfaces with the same security levels:
•Disabled—Communication between interfaces on the same security level is not allowed.
•Inter-interface—Enables traffic flows between interfaces with the same security level setting.
When this option is enabled, you are not required to define translation rules to enable traffic flow
between interfaces in the firewall device.
•Intra-interface—Enables traffic flows between subinterfaces with the same security level setting.
When this option is enabled, you are not required to define translation rules to enable traffic flow
between subinterfaces assigned to an interface.
•Both—Allows both intra- and inter-interface communications among interfaces and subinterfaces
with the same security level.
Step 2 Continue with Advanced Interface Settings (PIX/ASA/FWSM), page 45-42 configuration, or click OK
to close the Advanced Interface Settings dialog box.
Managing the PPPoE Users List
Point-to-Point Protocol over Ethernet (PPPoE) allows standard PPP communication between a security
device and an external ISP, via an Ethernet interface on the device. To establish a communication link,
the device must provide authentication credentials and obtain network parameters. This is accomplished
using a Virtual Private Dialup Network (VPDN) group, which basically consists of established PPPoE
user credentials (i.e., a user name and password) and an authentication protocol. See Managing VPDN
Groups, page 45-45 for more information about VPDN groups.
The PPPoE user credentials available for use with VPDN groups are maintained in the PPPoE Users
dialog box, which you can access from the Advanced Interface Settings (PIX/ASA/FWSM), page45-42
dialog box, and from the Add/Edit VPND Group dialog boxes.
Adding and Editing PPPoE Users
The PPPoE Users dialog box presents a table of currently defined PPPoE users, along with standard Add
Row, Edit Row, and Delete Row buttons. The Add Row button opens the Add PPPoE User dialog box;
the Edit Row button opens the virtually identical Edit PPPoE User dialog box.
Enter or edit the following PPPoE user parameters, and then click OK to close the Add (Edit) PPPoE
User dialog box and return to the Advanced Interface Settings dialog box.
Note PPPoE user options are not available on Firewall Service Modules (FWSMs).
