The adoption of 1:1 Network Address Translation (NAT) switches by OEMs (Original Equipment Manufacturers) is becoming increasingly popular, and their power and benefits are becoming more evident to control engineers. Although network and architect engineers have been aware of their capabilities for quite some time, control engineers are starting to experience the benefits firsthand. Today, I’ll review 1:1 NAT switches, exploring their definition, functionality, and why they have become crucial for OEMs - and stay tuned to discover the transformative Phoenix Contact technologies driving this revolution. Let's get started!

NAT offers numerous advantages worth considering. First up, 1:1 NAT switches facilitate seamless integration of a machine's network into a corporate or factory network. By changing IP addresses, NAT eliminates conflicts and ensures uninterrupted communication between devices from different networks. This becomes especially crucial when avoiding IP address clashes between machines and devices on plant networks. Most importantly, NAT contributes to network security by acting as a firewall, concealing private IP addresses behind a single public IP address. This added firewall layer of protection shields machines from direct attacks and unauthorized access attempts.
1:1 NAT switches are essential network devices that seamlessly integrate a machine's network into a corporate or factory network. NAT eliminates conflicts between devices across different networks by translating internal IP addresses into external ones. This ensures flawless machine delivery to the end user without any IP address clashes on the plant network. In essence, 1:1 NAT switches act as mediators, enabling smooth and harmonious communication between diverse networks.
The rise of Industry 4.0 and the Industrial Internet of Things (IIoT) is propelling the merging of industrial networks. As an example, factory floors today are experiencing a revolutionary shift as machines and devices seamlessly integrate into a unified network under the centralized control of a management system. Making necessary a departure from isolated networks for OEMs.
Here, utilizing 1:1 NAT switches presents an elegant solution to this challenge, offering OEMs the opportunity to effortlessly integrate their machines into plant networks with minimal complexity. Additionally, these switches empower OEMs with the flexibility to deliver machines to customers utilizing internal IP addresses, thereby mitigating any potential conflicts. With these advancements, industry professionals find themselves at the threshold of unlocking unprecedented efficiency and operational excellence.
As the benefits of network unification become more widely recognized, interconnectivity between machines has never been easier. By utilizing virtual local area networks (VLANs) in conjunction with 1:1 NAT switches, OEMs can segment and manage individual machines within their network. This capability not only provides superior control over machine access but allows for a greater degree of scalability and expansion.
When choosing the optimal 1:1 NAT switch for an OEM's machine, it is crucial to assess the factors carefully. These might include:
It is worth noting that many OEM machine manufacturers provide recommendations on NAT switches that have undergone extensive testing with their products. In deploying 1:1 NAT switches, OEMs should thoroughly evaluate the specific integration needs of both their machines and their customers. By doing so, they can ensure seamless performance and customer satisfaction.
To access the settings/configurator of your MGuard, follow these simple steps:
1. Connect an ethernet cable from your computer's ethernet port to the LAN port on your MGuard (the bottom port on your two-port router).
2. Open a browser and type in the default IP address (192.168.1.1). Please note that you might face difficulties accessing the web-based server (WBS) due to corporate network restrictions. If this happens, try restarting your computer and ensuring that you are not connected to a corporate VPN.
3. When accessing the web-based server, use the default login credentials "admin" for the username and "MGuard" for the password. For added security, it is recommended to change these credentials later.
4. Once you gain access, navigate to the left-hand menu column and click on Network<NAT to configure your NAT scheme based on your existing network.
5. If you need to establish rules for filtering incoming and outgoing data, you can do so at Network Security<Packet Filter. The provided screenshots will guide you to the firewall ruleset page.
6. You can use this device in “stealth mode,” preserving the existing network from changes. If the mGuard is in Stealth network mode, it is inserted into the existing network (see figure below) without changing the existing network configuration of the connected devices. Example Application: Activate stealth mode and set up a firewall to block all incoming and outgoing data with the exception of "MODBUS TCP" data. That way, the device is unrecognized on the network, only transmitting the needed communication protocol while filtering out unneeded information.
