XUELK-TN-001: Configuring SBC Lynx as industrial router
Introduction[edit | edit source]
Nowadays IP networks are become popular in industrial environments. To limit infrastructure costs, these networks are often built ased on-trivial routing configurations are needed
This article shows how to configure SBC Lynx to implement a router that manages data packet forwarding between two different LANs.
Network topology[edit | edit source]
The following image shows a simplified block diagram of the network topology that has been used for testing this configuration.
There are two LANs:
- main LAN (192.168.0.0/24)
- secondary LAN (192.168.11.0/24).
The following devices are connected to these LANs:
- a PC connected to the main LAN (IP address = 192.168.0.28)
2) main LAN switch 3) SBC Lynx equipped with two Ethernet interfaces a) primary interface (eth0) connected to main LAN (IP address = 192.168.0.209) b) secondary interface (eth1) connected to secondary LAN (IP address = 192.168.11.209)  4) secondary LAN managed switch (IP address = 192.168.11.239) 5) WiFi access point connected to secondary LAN (IP address = 192.168.11.241)
Secondary LAN managed switch and access point integrate a web server, accessible at port 80. Two IP forwarding rules have been be set up in order to make web servers accessible at 192.168.0.209:80 and 192.168.0.209:8080:
- 192.168.0.209:80 <-> 192.168.11.241:80
- 192.168.0.209:8080 <-> 192.168.11.239:80
 For simplicity, secondary interface has been implemented with an USB2Ethernet adapter (TBD). For a real-world production environment it is recommended the use of the iMX6UL
