Overview
WALL IE, the new Industrial Ethernet Bridge and Firewall, simply integrates your machinery network
into the higher-level production network. A packet filter protects the networks from unauthorized
access. If identical IP address ranges are to be realized, WALL IE functions as a bridge.
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.
WALL IE features:
•
Bridge functionality for identical IP address ranges
•
NAT (Basic NAT, NAPT and port forwarding)
•
Access restriction through packet filters: IPv4 addresses, protocol (TCP/UDP), ports
•
MAC addresses, black and whitelisting
•
Quick and easy configuration thanks to responsive web interface
•
Static routes to other networks
•
Reporting of events to a Syslog server
•
Export/import of configuration
•
Industry-compatible design for installation on DIN rails

Setup
The WALL IE has a 100 Mbps WAN port (P1) and three 100 Mbps LAN ports (P2-P4) that have been
switched.
A reset to factory settings can be initiated with the function button (FCN) (see ch. 11). The reset
button (RST) initiates a restart of the WALL IE.
