WALL IE – Industrial NAT Gateway/Firewall

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.


  • Low effort for IP integration in higher-level networks (NAT)
  • Integration of series machines with the same IP addresses in the production network
  • NAT (Basic NAT, NAPT und Portforwarding)
  • SNAT: No adjustment of the network configuration in the LAN network necessary
  • Access restriction through packet filters: IPV4 addresses, protocol (TCP/UDP/ICMP), ports, MAC addresses 
  • Reduction of the network load through the filtering of broadcasts and multi-casts
  • Quick and easy configuration via a responsive web interface
  • Easily integrate same IP subnets through port forwarding (NAPT)
  • Reduced to the essential functionality
  • Import and export of the configuration
  • DHCP-Server (LAN) / DHCP-Client (WAN)
  • DNS-Server (LAN)
  • User administration
  • Space-saving industrial design for DIN rail
