1 Safety instructions Target audience This description is only intended for trained personnel qualified in control and automation engineering who are familiar with the applicable national standards. For installation, commissioning, and operation of the components, compliance with the instructions and explanations in this operating manual is essential. The specialist personnel is to ensure that the application or the use of the products described fulfills all safety requirements, including all applicable laws, regulations, provisions, and standards.
Only the most important settings are explained. For a detailed description of all functions and important safety instructions, please refer to the WALL IE manual. This can be found at www.helmholz.de or scan the QR code directly. 3 Connecting the WALL IE The WALL IE must be supplied with DC 24 V at the wide range input 18-30 V DC via the supplied connector plug.
4 Initial access to the web interface The WALL IE is delivered from the factory with the IP address 192.168.0.100 and the subnet mask 255.255.255.0 on the LAN side. Access to the web interface is only possible via the P2 - P4 LAN ports. The IP address of your network adapter must first be set in accordance with the IP subnet of the WALL IE: Start ...
Please check the WALL IE website for a newer firmware version. The firmware update is described on page 18. Firmware link: http://www.helmholz.de/goto/700-860-WAL01#tab-software 6 Choosing the operating mode Depending on the application for the WALL IE, the operating mode must be defined at the beginning.
Basic NAT, also known as “1:1 NAT” or “Static NAT”, is the translation of individual IP addresses or of complete IP address ranges. With the help of port forwarding, it is possible as an alternative to configure those packets be forwarded to a particular TCP/UDP port of the WALL IE to a certain participant in the machine network (LAN).
7 Application „NAT“ To activate the NAT operating mode, select the “Operating Mode” menu point in the “Device” menu and set this to “NAT”. 7.1 Adjustment of the IP addresses in the NAT operating mode Click on the “Network” menu and select the sub- menu “Interface”.
7.2 Setting up “Basic NAT” rules To use Basic NAT functionalities, the operating mode of the WALL IE must be set to "NAT". Select the "NAT" menu and the "Basic NAT" submenu. Enter the first rule and save it using the button.
7.3 Packet filter “WAN to LAN” The packet filters can be used to restrict access between the company network (WAN) and the machine network (LAN). For example, it can be configured that only certain subscribers from the company network are allowed to exchange data with defined subscribers from the automation cell. The following filter criteria on layers 3 and 4 are available: IPv4 addresses, protocol (TCP/UDP/ICMP), and ports.
If a filter rule applies to several or even all ports, this can be simply defined in the “Destination Ports” field. A list of ports is indicated separated by commas: “80,443,1194”. A port range can be indicated with a colon “4000:5000” or “1:65535” for all ports. Combinations are also possible: “80,443,4000:5000”. It is also possible to configure the access of several participants with one another.
7.5 SNAT The function “SNAT (Source NAT)” transparently forwards incoming traffic from the WAN side to the LAN network. To all packets, forwarded on LAN side by WALL IE, source IP address is replaced with WALL IE LAN IP address. Therefore, none of the LAN participants needs the WALLIE LAN-IP as „gateway“.
7.6 NAPT “NAPT for LAN to WAN traffic” replaces the sender addresses of queries from the LAN with the WALL IE WAN IP address. Source IP 10.10.1.1:xxx Source 192.168.10.1:80 The option “NAPT: Active” thus enables communication of devices from the LAN with devices in the WAN.
7.7 Portforwarding With the help of port forwarding (“Port forwarding for WAN to LAN traffic”), it can be configured that packets at a certain TCP/UDP port of the WALL IE (WAN) can be forwarded to a participant in the LAN (e.g. 10.10.1.1:81 to 192.168.10.5:80).
8 Application “Bridge” To activate the bridge operating mode, select the "Operating Mode" menu item in the "Device" menu and set it to "Bridge". 8.1 Adjustment of the IP addresses in the bridge operating mode Click on the “Network” menu and select the sub-menu “Interface”. The IP addresses of the WALL IE (“LAN IP”) and affiliated subnet mask (“LAN netmask”) can be defined here.
8.2 Packet filter “WAN to LAN” The packet filters enable the limitation of access between the company network (WAN) and the machine network (LAN). For example, it can be configured that only certain participants from the company network may exchange data with defined participants in the automation cell.
If a filter rule applies to several or even all ports, this can be simply defined in the “Destination Ports” field. A list of ports is indicated separated by commas: “80,443,1194”. A port range can be indicated with a colon: “4000:5000” or “1:65535” for all ports. Combinations are also possible: “80,443,4000:5000.” It is also possible to configure the access of several participants with one another.
