Bridge help

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

If you start the YunServer using the constructor with the port parameter, you can connect to your yun using whatever port. Don't forget to call function "noListenOnLocalhost"

Thanks for your help. Please could you point me to the documentation on how to start the YunServer with the constructor with the port parameter? Or provide an example line of code?

Thanks, Anthony
