1783-NATR Manual: An Overview

The 1783-NATR Configurable NAT Router is designed to seamlessly connect private networks to larger plant-wide networks without necessitating IP address changes. It uses simple 1:1 Network Address Translation, facilitating secure communication between different network segments.

Purpose of the 1783-NATR Device

The primary purpose of the 1783-NATR device is to serve as a secure and efficient gateway between a private network, such as a machine network with embedded controllers, and a larger public or plant-wide network. This connection is achieved without exposing the entire private network. The 1783-NATR translates private IP addresses to unique public IP addresses using 1:1 NAT, protecting the internal network from direct exposure to external threats. This is particularly useful when remote controllers are integrated with HMIs, drives, or other devices, preventing the need to expose the entire private network to the facility PLC network. The 1783-NATR device acts as a default gateway for the private network, ensuring that only authorized and translated traffic can pass through, enhancing security and simplifying network management. It allows devices on the private network to be accessible from the public network.

Network Address Translation (NAT) Functionality

The 1783-NATR device employs Network Address Translation (NAT) to enable communication between devices on different IP networks, primarily between a private network and a public network. The core function of NAT within the 1783-NATR is to translate private IP addresses used within the internal network to unique, routable public IP addresses. This translation is typically a 1:1 mapping, meaning each device on the private network is assigned a corresponding public IP address for external communication. When a device on the private network needs to access the public network, the 1783-NATR replaces the device’s private IP address with its assigned public IP address. Conversely, when external devices need to access resources on the private network, the 1783-NATR translates the public IP address back to the corresponding private IP address, routing the traffic to the correct internal device. This process effectively hides the internal network’s IP addressing scheme from the outside world, enhancing security and simplifying IP address management.

Key Features and Specifications

The 1783-NATR boasts key features like 1:1 NAT mapping, support for up to 32 translations, and a performance capability of 25,000 Packets Per Second (PPS) during high-performance testing.

1:1 NAT Mapping

The 1783-NATR device employs 1:1 Network Address Translation (NAT), a fundamental feature that maps private IP addresses to unique public IP addresses. This ensures that each device on the private network can have a corresponding, distinct presence on the public network, allowing for targeted communication. If a device within the private network requires accessibility from the public network, a specific translation is created on the 1783-NATR, enabling external access to that device;

This 1:1 mapping is crucial for maintaining network security and simplifying network management. It allows for controlled exposure of specific devices while keeping the rest of the private network shielded. This method is particularly useful in industrial automation settings where remote access to certain controllers or HMIs is needed without exposing the entire machine network. The 1783-NATR acts as a secure gateway, translating addresses as needed and providing a controlled interface between the private and public domains.

Maximum Translation Mappings (Up to 32)

The 1783-NATR Configurable NAT Router supports a maximum of 32 translation mappings, allowing for the management of up to 32 devices with unique public IP addresses from a private network. This capacity is suitable for small to medium-sized machine networks where a limited number of devices require external accessibility. This limitation ensures that the device can efficiently handle the translation load while maintaining optimal performance.

Each translation mapping corresponds to a 1:1 NAT rule, associating a specific private IP address with a corresponding public IP address. When planning a network implementation, it’s crucial to consider the number of devices needing external access to ensure that the 32-translation limit is sufficient. Exceeding this limit would require alternative network configurations or additional NAT devices. The 1783-NATR’s capacity is designed to balance functionality with cost-effectiveness for typical industrial applications.

Packets Per Second (PPS) Performance

The 1783-NATR Configurable NAT Router’s performance is measured in Packets Per Second (PPS), indicating its ability to process network traffic.
