Can't reach 172.16.16.16 on my brand new XG 105 hardware firewall

Hi Michele Dal Corso 

Welcome to the Sophos Community!

To rule out the possibility of an pre-existing configuration stored in your new firewall causing issues and to confirm default settings:

• I would advise to first attempt accessing the CLI of the device via monitor/keyboard or with the provided console cable.
  • Attempt using the default admin credentials of username: admin and password: admin
• If the default credentials don't work.
  • Use this KB to reset the admin password

After accessing the CLI, you should be able to verify the configured interface network settings via 1.) Network Configuration > 1.) Interface Configuration

Note that you can also perform a factory reset of the appliance to ensure you won't run into issues with any pre-existing configuration settings.

Best,
