Wake-on-LAN support in Parallels Access 2.0

APPLIES TO:
  • Parallels Desktop
  • Parallels Access

Information

Parallels Access 2.0 (and later) supports the Wake-on-LAN feature that wakes your sleeping Mac or PC remotely when you need to access it via Parallels Access.

Parallels Access 2.0 takes advantage of several technologies to do this, depending on your operating system:

  1. Apple Power Nap:

    This feature works on most Apple computers released since late 2010 with OS X 10.8 or later. It requires the “Enable Power Nap” option to be active (it’s on by default) in the Energy Saver settings.

    Parallels Access uses Power Nap’s semi-sleep mode to maintain the connection between the remote computer and Parallels servers. If the Parallels Access mobile app tries to connect to the computer, it will wake the computer and a connection will be established.

    This feature will work even if your MacBook Pro® or Air® laptop is closed.

    Important: The Power Nap feature will work only if your Mac is connected to the power source.

  2. Intel Smart Connect (ISCT)

    Intel® Smart Connect Technology (ISCT) is a proprietary tool similar to Apple Power Nap. It works only on Windows PCs with certain Intel CPUs and Intel chipsets manufactured starting in 2013, and it requires BIOS support.

    Depending on the computer’s manufacturer and configuration, it may be enabled or disabled by default.

    To enable ISCT support in BIOS, check one of the following BIOS menu items (depending on the BIOS version):

    • Advanced > PCH Configuration > Intel Smart Connect Technology > ISCT Configuration
    • Advanced > Intel Smart Connect Technology > Intel Smart Connect Technology
    • Settings > Advanced > Intel Smart Connect Technology

    ISCT also requires installing a utility that is available for Windows 7, 8 and 8.1. On most recent Windows computers that support ISCT, all necessary softwar should be installed by default. You can also download it from the Intel website.

    For more details on ISCT support, contact your computer’s manufacturer.

  3. Waking up over a local network

    On Mac:

    Most Mac computers support both Wake-on-Ethernet (WoL) and Wake-on-WiFi (WoWLAN).

    To enable WoL/WoWLAN, open System Preferences-> Energy Saver and enable the option "Wake for network access", "Wake for Ethernet network access" or "Wake for Wi-Fi network access", depending on the computer configuration.

    To see if your Mac supports WoWLAN:

    • While holding down the option key, click the Apple menu and select System Information…

    • In the Network section, click Wi-Fi.

      "Wake on Wireless" should be "supported".

    To know more about the Wake-on-LAN for Mac, see this Apple KB article.

    On PC

    In Windows, Wake-on-LAN can be enabled by configuring the network adapter: Control Panel -> Device Manager -> Network Adapters -> <LAN Adapter> -> Power Management -> "Allow this device to wake the computer"

    Note: In some cases, changing BIOS settings related to the Wake-on-LAN feature is required on Windows computers.

  4. Bonjour® Sleep Proxy

    Certain Apple devices, such as AirPort Express®, AirPort Extreme® Base Station, AirPort Time Capsule®, Apple TV®, and Mac computers running OS X 10.6 or later, can operate as helpers in a local network to wake up a sleeping computer.

    To learn more about Bonjour Sleep Proxy feature, see this Apple KB article.

  5. Waking up over the Internet

    UPnP and NAT/PMP are similar technologies that allow remote computer to be woken up over the internet. This works for most home internet connections that use routers with NAT, but it will not work for corporate networks.

    UPnP/NAT-PMP will work only in cases where there is a single NAT between the computer and the Internet. Make sure your Internet service provider assigned a permanent external IP address to your home network.

    Most network routers made in 2012 or later have UPnP enabled by default and will provide appropriate port forwarding from external an IP address to a local IP address. Also confirm that the following port ranges are enabled:

    • UPNP: Allowed internal port range – 1­-65535

    • NAT-PMP: Allowed external port range – 1­-65535

    AirPort and Time Capsule routers support NAT-PMP. To enable it, launch Airport Utility -> NAT/Network -> select “Enable NAT Port Mapping Protocol”.

See KB122348 for more information about configuring NAT manually.
