Why are you using Network library v1.10? This is an old version. The current version is 1.51.

 

[gregorio_adrian_gimenez]

thanks you, is correct I used v 1.10 ,

But I do not get it to work with two devices on different local networks, is there any way to do it?
regards

Only if the routers are configured to forward the packets to the correct destination.
