Secure communication and simple addressing – WALL IE protects your automation network against unauthorized access. Due to the individual configuration, the firewall can be easily adapted to the requirements of the respective machine network.
The NAT operating mode serves the forwarding of the data traffic between various IPv4 networks. It enables the address translation via NAT and uses packet filters for the limitation of access to the automation network located behind.
In the bridge operating mode, WALL IE acts as a layer 2 switch. In contrast with normal switches, however, packet filtering is also possible in this operating mode. This means that the restriction of access to individual areas of your network can be achieved without having to use different networks for this purpose.
