I had an Arduino with an Ethernet shield. I used Mudbus to create a mod bus server, accessing it using scadamobile from an iPhone and iPad. Works very well. Now I want to repeat this using a Yun.
My problem is that the IOS app scadamobile talks to the Arduino with a tcp/ip address e.g. 192.168.1.100 using port 502.
The Yun only forwards data to the arduino using 192.168.1.100/arduino on port 80
I can't tell scadamobile to use the suffix /arduino
How can I configure the Yun to pass requests on port 502 directly without requiring the /arduino suffix?
Thanks, Anthony
