Hello!
I managed to solve my problem.Firstly i noticed that my windowsVM had an expired license,so I recovered the first snapshot.Then i tried again and everything worked perfectly.I also stopped the program before the execution of echo command.I don’t know if those two properties were the actual problem,or if it was some network issue
that didn’t occur further,anyway it works know.Thanks for the iptables commands, I think they might be useful if I encounter similar problems.
Best regards!
