When i m trying access from my mobile while first i have configured a port forwarding for ex. 5555 giving the order 192.168.1.70:5555/arduino/digital/13/1 nothing happens
check if i have to make any changes in the configuration of my arduino yun board network settings....
...Now, some caveats - even if you set up the router properly, there is still a chance that it won't work. It all depends on your Internet Service Provider (ISP) and what rules they impose. Some ISPs will allow incoming connections on any port. Some will block a few ports, some will block most ports, and some will block all ports.
It is ture. But it is seem all the ISPs leave port 22 or 2222 open since they need them to manage their own equipment on network.
I have also personally run into the situation where a cellular Internet device was issued a private (non-routable) address from the ISP. Outbound connections could be made, and I'm sure the ISP could make inbound connections to the device using the private address that their router hands out, but I could never make an inbound connection on my own to the device - to do so, I would've had to have access to the ISP's upstream router and create a port forward on that router: something I clearly could not do.My point wasn't to dwell on details, but only to point out that in some situations you can set everything up properly, and still not be able to make an incoming connection. In the case of the cellular Internet device just mentioned, that was the Internet access method for the whole house, so during the few years I had that device I could never make any sort of incoming connection.
