I am trying to make my Arduino visible on the internet. I have a Linksys router and have programmed a port forward from external to internet (external for example 123 pointet to internal 80) unfortunately nothing happens when I type my Ip-adress followed by :123 - nothing happens. If i test my ip-adress i get my NAS server, I think it is responding on port 80 (?)
How can I change Arduinos port to a different one 8090 for example? (I have tried the example code but then the Arduino does not show ip internal on its IP dress (192.168.1.64) The router is programmed to forward xx.xx.xx.xx:123 to 8090 - nothing happens.
kind regards Karsten
