1 Introduction
1.1 Industrial Ethernet Firewall
1.1.1 Application areas
The EAGLE industrial firewall/VPN system ensures the authentication, secu-
rity and confidentiality of communication within production networks, but also
beyond company boundaries.
The EAGLE supports the following network modes:
X
Transparent Mode
X
Router Mode
X
PPPoE Mode
1.1.2 Operating modes
This device protects the network to be secured (secure port) from external
influences (non-secure port). These influences can include deliberate attacks
or unauthorized access attempts, as well as interfering network events such
as overloads.
„
State on delivery
On delivery, the device works in the Transparent Mode. In this mode, no
network settings (e.g., for subnetworks) are required for operation.
The firewall has been preconfigured so that all IP traffic from the secure
network is possible; however, traffic from the insecure network to the se-
cure one is not possible. Thus, already in the delivery state, external at-
tacks on the secure network are not possible.
„
Modes
X
Transparent Mode
In transparent mode, the Firewall transmits on level 2 of the ISO/OSI
layer model. The IP address ranges before and after the Firewall are
located in the same subnetwork.
In the state on delivery, you can access the device via address
192.168.1.1/24 without configuring the IP address.
