Introduction

The NAT-G102 Series is an industrial Gigabit NAT device designed to simplify the IP configuration of machines in existing network infrastructure in factory automation environments. The NAT-G102 Series provides complete NAT functionality to help machines adapt to specific network scenarios without complicated, costly, and time-consuming configurations. Featuring Gigabit Ethernet connectivity, the NAT-G102 Series enables higher data throughput for modern industrial applications while also protecting the internal network from unauthorized access by outside hosts.

Quick and User-friendly Access Control

The NAT-G102 Series’ Auto Learning Lock feature automatically learns the IP and MAC address of locally connected devices and binds them to the access list. This feature not only helps you manage access control but also makes device replacements much more efficient.

Industrial-grade and Ultra-compact Design

The NAT-G102 Series’ rugged hardware makes these NAT devices ideal for deployment in harsh industrial environments, featuring wide-temperature models that are built to operate reliably in hazardous conditions and extreme temperatures of -40 up to 75°C. Moreover, the ultra-compact size allows the NAT-G102 Series to be easily installed into cabinets.
