Chapter 5: Configuring the CopperJet
5.7.2 Configuring Security Interfaces
Before Security options can be configured, there must be at least 2 Security interfaces
defined and configured. Security interfaces represent the logical connections to and from
the CopperJet. These interfaces are used to enable the security on these connections.
There are three different types of security interfaces available
• Internal: usually the LAN connection
• External: usually the WAN connection
• DMZ: usually a second LAN connection or IP subnet
Note: The security interfaces are directly linked to the LAN and WAN connections. Be sure
that the necessary LAN and WAN connections are configured correctly. The security
interfaces can be assigned to these connections.
Important: When a WAN connection is already configured with NAT enabled, both
the internal and external Security Interfaces are automatically added
and configured. These Security Interfaces can be used to enable the
other security options.
To add a Security Interface, go to the Configuration menu and select Security. The
Security Interface Configuration page is displayed. Select Add Interface at the Security
Interface section. The Firewall: Add interface page is displayed.
Select the proper WAN or LAN connection from the Name section.
• The Ethernet LAN connection is represented as ethernet-0.
• The USB LAN connection is represented as ethernet-1.
• WAN connections are represented as ppp-0, rfc1483-0, or ipoa-0.
Select the proper Interface type. Usually the LAN connections ethernet-0 or ethernet-1 are
internal. The WAN connections are usually external.
Click on Apply to add the security interface.
The Security Interface Configuration page is displayed and the security interface is added
to the section Security Interface.
