We are using the LAN port to connect to our devices through an USB to ETHERNET converter but in the high temperature the converter needs to disconnect from the host and reconnected to operate in good way, our system is a SCADA system and working 24/7 .
I think if we used either the USB to serial or RS 232 with all the features of the LAN port, specially port forwarding.
Please assure me if we can use the port forwarding ( forward 10 ports ) with either of these methods and which is higher speed and more dependable, then please refer me the right way to configure the ROUTER to be tested.
