The EDR-G903 series is a Gigabit performance, all-in-one Firewall/VPN/Router. It is designed for Ethernet security applications in sensitive remote control or monitoring networks, and provides an Electronic Security Perimeter for the protection of critical cyber assets. The EDS-G903 series Cyber Security features include:
Firewall: Controls network traffic between different trust zones.Network Address Translation (NAT), which shields the internal LAN from unauthorized activity from outside hosts, is included.
Virtual Private Networking (VPN)*: VPNs are designed to provide users with secure communication links when accessing a private network from the public Internet. Uses IPSec (IP Security) for encryption and authentication of all IP packets at the network layer to ensure confidentiality and sender authentication.
The EDR-G903 supports one WAN, one LAN, and a userconfigurable WAN/DMZ interface that provides high flexibility in different applications such as WAN redundancy or Data/FTP server security protection. The EDR-G903's Quick Automation Profile function supports most common Fieldbus protocols, including EtherCAT, EtherNet/IP, FOUNDATION Fieldbus, Modbus/TCP, and PROFINET. Users can easily create a secure Ethernet Fieldbus network from a user-friendly web UI with a single click operation. In addition, wide temperature models are available that operate reliably in hazardous, -40 to 75°C environments.
