4G router INSYS icom MRX3 LTE with Fast Ethernet, BGP/OSPF/RIP routing, IPSec/SNMP/SSH security

Industrial 4G router INSYS icom MRX3 LTE provides reliable cellular connectivity with LTE and legacy 3G/2G protocols (HSPA, UMTS, EDGE, GPRS) and a Fast Ethernet LAN interface (10/100 Mbps). The device supports dynamic routing protocols including BGP, OSPF and RIP/RIP-2, and implements security features such as IPSec VPN, SNMP monitoring, SSH access and RADIUS authentication. The MRX3 is designed for industrial and enterprise environments, offering modular expandability, KRITIS-level security measures and compliance with CE and common EMC and safety standards.

Advantages

The MRX3 LTE combines cellular and wired networking in a compact industrial form factor, offering flexible expansion via plug-in MRcards and dual digital inputs for integration with automation systems. High computing power and programmable administration enable advanced routing, firewall and VPN functions on site. Built-in security features such as IPSec, SSH and RADIUS support secure remote access and management, while SNMP allows centralized monitoring. The router’s modular design and available housing options make it adaptable to changing network requirements and future technology upgrades.

How to use

Install the MRX3 LTE in a suitable industrial cabinet or DIN-rail location and connect the Fast Ethernet port to your local network switch or device. Insert the approved SIM card and configure APN and cellular settings through the web interface or management software. Define routing protocols and establish VPN tunnels using the router’s administration console, and configure SNMP and RADIUS if centralized monitoring and authentication are required. Add MRcards as needed for extra interfaces and adapt firewall and NAT rules according to your network topology.

Recommendations

For stable cellular performance, use an external antenna appropriate for the LTE bands in your region and place the router where signal strength is optimal. Keep firmware up to date to maintain security and protocol compatibility. When deploying in critical environments, configure redundant routing or failover policies and regularly back up the router configuration.
