Industrial Network Security and Management
EDR-G903 Series
The EDR-G903 series is a high performance, industrial VPN server 
with firewall/NAT all-in-one secure 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 includes the 
following cyber security features:
•  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) server 
or client mode for encryption and authentication of all IP packets at 
the network layer to ensure confidentiality and sender authentica-
tion.
Industrial VPN secure routers, 2 WAN/1 DMZ,
firewall/NAT, 25 VPN tunnels
•  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.
The EDR-G903 supports one WAN, one LAN, and a user-configurable 
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.
