• 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.

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. The connection (FE) is for the functional earth. Connect it properly to the reference potential. The WALL IE is designed exclusively for operation with safety extra-low voltage (SELV/PELV).

• The RJ45 socket “P1 WAN” of the WALL IE (700-860-WAL01) is used to connect the external network. The RJ45 sockets “P2 LAN-P4 LAN” are switched and are used to connect the internal network.

• The RJ45 sockets “X1 P1” to “X1 P8” of the WALL IE PLUS (700-862-WAL01) can be assigned to the network WAN or LAN as desired. In the factory setting, port

• P1 is set for WAN and ports P2-P8 for LAN. The LEDs next to the port indicate the assignment, orange for WAN and green for LAN. Setting the assignment of the ports for WAN and LAN is possible in the web interface. More detailed information can be found in the manual.

• The WALL IE Compact (700-863-WAL01) has a socket “X1 WAN” at the top for the external network and a socket “X1 LAN” at the bottom for the internal network.

• The inputs IN1 and IN2 of the WALL IE and WALL IE PLUS have no function in the current firmware version but will be available for external switching of firewall rules in a later firmware version.

• The WALL IE Compact has no inputs.

• NOTE
  The housing of the WALL IE is not grounded. Please connect the functional earth connection (FE) of the WALL IE properly to the reference potential.

• NOTE
  The device may only be operated with power supplies that meet the specifications of EN 62368-1 for power sources of limited capacity. Otherwise, the device must be operated in an enclosure that meets the requirements of a fire protection enclosure according to EN 62368-1.

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 possible with the WALL IE (700-860-WAL01) via the LAN ports P2 – P4. With the WALL IE PLUS (700-862-WAL01), access is possible via the ports P2 – P8 or via all ports whose LED lights up green in the delivery state. With the WALL IE Compact, the web interface can be accessed via “X1 LAN”.

• First, the IP address of your network card must be set according to the IP subnet of the WALL IE. In the network settings of the network adapter, set the subnet mask and the IP address of the PC to match the default IP address of the WALL IE, e.g. 196.168.0.1 with subnet mask 255.255.255.0.
• Now connect a patch cable with the LAN connection of your PC and one of the LAN ports of WALL IE.
• The web interface can be reached in the delivery condition by entering URL “https://192.168.0.100” in the browser page.
• NOTE
  For security reasons, the web interface can only be reached through a secured HTTPS connection. An exception rule must be confirmed in the browser once to reach the website. A certificate for the connection backup can be stored in the “Device/HTTPS” menu.

With the first login you will be requested to set a password for the “admin” user.

• The password must contain at least 8 characters and can be up to 128 characters long, it can contain special characters and numbers. With the button
• “Continue” the password will be saved in the device and you will be redirected to the “Overview” page of the WALL IE.
• The main user is always “admin”.
• In addition to the main user, the “it-user” and “machine-user” can also be used with limited rights.
• The users can be activated, and the affiliated passwords set in the “Device/Password” menu.

NOTE
Please memorize the password carefully! For security reasons, there is no way to reset the password without setting the device to factory settings.

Main view

• The “Overview” website of the WALL IE always opens after the login. The
• “Overview” main view contains an overview of the most important settings and information of the WALL IE.
• The topmost line contains the menu with the functions for configuration.

NOTE
Please check the WALL IE website for a newer firmware version. The firmware update is described on page 19.

Choosing the operating mode

Depending on the application for the WALL IE, the operating mode must be defined at the beginning. WALL IE supports two basic modes of operation: NAT and Bridge.

1. The NAT operating mode
   When an automation cell with preset IP addresses is to be incorporated into a company network with other IP addresses, the IP addresses of the machine must normally all be set again.

   • When using Network Address Translation (NAT), WALL IE offers the possibility to leave the IP addresses of the machine as they are, but to enable communication with the machine network with own IP addresses from the company network.
   • In the NAT operating mode, WALL IE forwards the data transfer between various IPv4 networks (Layer 3) and exchanges the IP addresses with the help of NAT.
   • Packet filters and MAC address filters can also be configured to control the data transfer permitted.
   • Broadcast traffic is generally filtered at the WALL IE, which means that the time behavior of the machine network is not impaired by the company network.

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).
• The NAT operating mode thus also allows the integration of several automation cells that use an identical IP address range into the same Company network.
• Each automation cell can be assigned different free IP addresses from the company network.
• If “NAT” is your planned application case, please continue reading on page 9.

The Bridge operating mode

• In the Bridge operating mode, WALL IE behaves like a layer 2 switch between the machine network (automation cell) and the company network. The IP addresses in the company network are in this case in the same IP address space (subnet) as the addresses in the machine network.
• Access between the two network areas can be limited or secured with packet filters and MAC address filters.
• This allows the separation of part of the company network without using different network addresses.
• If “bridge” is your planned application case, please continue reading on page 16.

Application „NAT “
To activate the NAT operating mode, select the “Operating Mode” menu point in the “Device” menu and set this to “NAT”.

1. Adjustment of the IP addresses in the NAT operating mode

   • Click on the “Network” menu and select the sub-menu “Interface”. The IP addresses of the WALL IE in the WAN and in the LAN (“WAN IP”/”LAN IP”), as well as the affiliated subnet masks (“WAN netmask”/”LAN netmask”) can be defined here.
   • A DNS server and a default gateway can also be indicated. This is necessary when devices from the LAN should reach the Internet via the WALL IE. If these are not indicated (“0.0.0.0”), then communication of devices in the LAN with the Internet is prevented. It is necessary to indicate a DNS server for the SNTP service.
   • Optionally, the WAN-IP settings, the DNS server, and the default gateway can also be obtained using DHCP.
   • The entry is saved with the “Submit” button and the IP settings are then activated immediately. The current entry is rejected without acceptance with “Decline”.
   • ATTENTION
     If you change the LAN IP address, you may need to reopen the WALL IE web page on the browser under the new IP address and log in again.

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.

The “External IP” is a free IP address from the WAN IP address range. This must not have been assigned to any other Ethernet station (in the WAN) yet! The “Internal IP” is the existing IP address of the network node in the machine (LAN). As “Comment” any text can be entered. With this ‘additional WAN interface’ the address conversion (“natting”) to the entered LAN IP (the target device) is then realized in the WALL IE.

• Status: = Rule is active, a click on the lamp symbol changes the rule status to inactive
• = Rule is inactive, a click on the lamp symbol changes the rule status to active
• Possible actions: delete a rule edit a rule copy a rule

In the case of a “Basic NAT” rule, all ports for “WAN to LAN” data transfer are initially blocked for this rule for security reasons! In order to enable access, packet filter rules must be created or the default action for the packet filters be set to “Accept”. The “LAN to WAN” data transfer is initially always enabled but can also be limited by packet filters rules or the default action.

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.
• Click on the “Packet Filter” menu and select the sub-menu “WAN to LAN”.
• With the “Default Option” you can set whether all frames are generally allowed (“Accept”) and only special packets are filtered (“Blacklisting”), or  whether all \ frames are generally prohibited (“Reject” / “Drop”) and only those frames are allowed to pass through that correspond with the filter rules (“Whitelisting”).
• If you initially do not wish to filter, set the default action to “Accept”.
• In order to limit access to the machine network to certain participants in the WAN, set the default action to “Reject” or “Drop”. In the case of prohibited frames from the
• WAN, “Reject” sends an error message in response, while
• “Drop” rejects the frame without sending an error message.
• Example: A PC in the company network (WAN) has the IP address 10.10.1.10 (e.g. a visualization).
• This PC should be able to access the CPU with the IP address 192.168.10.1 within the LAN via the port 102 with the help of the TCP protocol.

Now enter the following rule and save it with the button.

• Source IP indicates the IP address of the active device in the company network (WAN).

• Destination IP specifies the addressed device in the machine network (LAN).

• The filter rules can be defined for one protocol type with protocol “TCP”, “UPD” or “ICMP”.

• Destination Ports indicates the ports to which the filter rules apply.

• 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. An IP range can be defined with a dash: “10.10.1.10-10.10.1.20“. A list of IP addresses is indicated with commas:
  “10.10.1.10,10.10.1.15,10.10.1.20”. IP subnet can be also declared using CIDR notation: “10.10.1.10/24”.

• Action defines whether this rule allows communication (“Accept”), rejects with error message (“Reject”), or simply rejects (“Drop”). The appropriate method here should always be chosen in interaction with the “Default Action”. If the Default Action is, for example, “Reject” or “Drop”, the filter rules should all be set to “Accept” (Whitelisting). If the Default Action is “Accept”, a block can be defined in the filter rules with “Reject” or “Drop” for certain devices (Blacklisting).

Packet filter “LAN to WAN”
By default data traffic is permitted for devices from the machine network (LAN) to the company network (WAN) without limitations (“Default Action”: “Accept”). ****

• General rule can be changed by setting the “Default Action” to “Reject” or “Drop”. In addition to general rule, filtering can be further customized using specific packet filter rules.”
• The entry of the filter rules corresponds to the “WAN to LAN” packet filter rules, the source IP now indicates the IP address of the active device in machine network (LAN), and destination address represents the device in company network (WAN).

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“. This is a considerable advantage when integrating into existing network structures since the parameters no longer have to be changed here.

NAPT
“NAPT for LAN to WAN traffic” replaces the sender addresses of queries from the LAN with the WALL IE WAN IP address.

• The option “NAPT: Active” thus enables communication of devices from the LAN with devices in the WAN.
  WALL IE thereby acts as a gateway to administer the implementation to the IP addresses of the WAN network and looks after the assignment of the response.

• NOTE
  In order for the communication from LAN to WAN to work when NAPT is activated, the WALL IE LAN IP address must be entered as gateway in all devices on the LAN!

• If the NAPT option is deactivated, the query packets from the LAN are forwarded from the LAN to the WAN with their original sender IP and sender port.

Port forwarding

• 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).
• In the following example, the website (Port 80) of the CPU with the IP 192.168.10.5 via WAN can be reached through access to the WALL IE-own IP address
• 10.10.1.1 with Port 81.
• Protocol: “TCP” or “UDP”
• External port: Port number through which the device on LAN side is accessed. On LAN side, device is accessed using internal IP address and internal port number.
• Internal IP: IP address of device connected to LAN.
• Internal Port: Port used to access device connected to LAN.
• Comment: Freely definable comment.
• NOTE
  “Port forwarding” and “Basic NAT” can be used simultaneously in NAT operating mode. If the default action for the “WAN to LAN” packet filters is set to “Reject” or “Drop”, corresponding filter rules for access must also be created for each port forwarding entry.

Application “Bridge”

To activate the bridge operating mode, select the “Operating Mode” menu item in the “Device” menu and set it to “Bridge”.

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.

• A DNS server and a default gateway can also be indicated. This is necessary when devices from the LAN should reach the Internet via the WALL IE. If these are not indicated, then communication of devices in the LAN with the Internet is prevented.
• The entry is saved with the “Submit” button and the IP settings are thus activated immediately. The current entry is rejected without acceptance with “Decline”.

NOTE
If you change the LAN IP address, you may need to reopen the WALL IE web page on the browser under the new IP address and log in again.

• In bridge mode, all ports are initially blocked for “WAN-to-LAN” data traffic for security reasons! To allow access, packet filter rules must be created or the “Default Action” for
  the packet filters must be set to “Accept”.

• LAN to WAN traffic is always enabled by default but can also be restricted by packet filters or the default action.

• A DHCP client or a DHCP server are not available in the bridge operating mode.

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.

• The following filter criteria on layers 3 and 4 are available: IPv4 addresses, protocol (TCP/UDP/ICMP), and ports.

• Select the “WAN to LAN” menu point in the “Packet Filter” menu.

• With the “Default Option” you can set whether all frames are generally allowed (“Accept”) and only special packets are filtered (“Blacklisting”), or whether all frames are generally prohibited (“Reject” / “Drop”) and only those frames are allowed to pass through that correspond with the filter rules (“Whitelisting”).

• If you initially don’t wish to filter, set the default action to “Accept”.

• In order to limit access to the machine network to certain participants in the WAN, set the default action to “Reject” or “Drop”. In the case of prohibited frames from the

• WAN, “Reject” sends an error message in response, while

• “Drop” rejects the frame without sending an error message.

• Example: A PC in the company network (WAN) has the IP address 10.10.1.11 (e.g. a visualization).

• This PC should be able to access the CPU with the IP address 10.10.1.30 within the LAN via the port 102 with the help of the TCP protocol.

• Now enter the following rule and save it with the  button.

• Source IP indicates the IP address of the active device in the company network (WAN). Destination IP the addressed device in the machine network (LAN).

• The filter rules can be defined for one protocol type with protocol “TCP”, “UPD” or “ICMP”. Destination Ports indicates the ports to which the filter rules apply.

• 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. An IP range can be defined with a dash: “10.10.1.10-10.10.1.20“. A list of IP addresses is indicated with commas:
