Industrial NAT Gateway and Firewall

The Helmholz WALL-IE offers secure communication and simple addressing, whilst offering protection of your automation network against unauthorised access. Due to the flexible configuration, the firewall can be easily adapted to the requirements of the 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. In the bridge operating mode, WALL IE acts as a layer 2 switch, again with packet filtering being possible. This means that the restriction of access to individual areas of your network can be achieved without having to use different networks.
