    First DNS resolver to use for the clients: 4.2.2.1
    Second DNS resolver to use for the clients (optional): 4.2.2.2

    You will be able to generate a client at the end of the installation.
    Press any key to continue...
  5. Press any key to initiate package installation and configuration script.
  6. Once packages are installed, setup client user (used for client connections):
    Tell me a name for the client.
    The name must consist of alphanumeric character. It may also include an underscore or a dash and can't exceed 15 chars.
    Client name: wgadmin
    Client's WireGuard IPv4: 10.66.66.2
