Industrial NAT Secure Router

Model: R2111

 

Product Overview

Designed to securely bridge OT and IT networks, providing robust, high-performance connectivity with five Gigabit Ethernet ports.

● Simplified OT & IT Integration:

Streamlines network setup with powerful NAT, routing functions, and IP Passthrough, easily connecting industrial equipment to enterprise networks.

● Comprehensive Network Security:

Runs on the hardened, penetration-tested Linux based RobustOS. Protects critical assets with a robust stateful firewall (including DMZ & anti-DoS) and supports secure VPN tunnels (IPsec, OpenVPN, DMVPN, GRE, Wireguard, etc.).

● Simplified Cloud Management:

Integrates fully with the RCMS cloud platform for fleet-wide monitoring, OTA updates of both the OS and applications running in containers, and secure remote access to end devices like PLCs, dramatically reducing operational costs.
