Hi thanks for your answer but that didnt solve the problem, let me explain again what is happening: If the raspberrpi lose the internet connection it doesnt reconnect back to the hamchi tunnel once it connect back to the internet, i think there must be an issue with the client itself.
So i think to solve this issue is to make an script that automatically restart hamachi service if pinging my hamachi ip local adress timeout, how can i do this?
