WALL IE, Industrial Ethernet Bridge and Firewall

WALL IE, Industrial Ethernet Bridge and Firewall

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

  • Bridge function for identical IP address ranges
  • NAT (Basic NAT, SNAT, NAPT and port forwarding)
  • Access restriction through packet filters: IPV4 addresses, protocol (TCP/UDP), 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
  • Static routes to other networks
  • Reporting of events to a Syslog server
  • Import and export of the configuration
  • DHCP-Server (LAN) / DHCP-Client (WAN)
  • User administration
  • Industry-compatible design for mounting on a DIN rail
  • Integration of machine networks into the higher-level plant network
