“Wake-on-LAN” support in Parallels Access 2.0

  • Parallels Desktop
  • Parallels Access


Parallels Access 2.0 supports Wake-on-Lan feature to wake your sleeping computer (a Mac or a PC) remotely when you need it to work with using Parallels Access.

Parallels Access 2.0 takes advantage of several technologies that help do this, both on Macs and on PCs.

  1. Apple's Power Nap

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

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

    This feature will work even if the lid of your MacBook (Pro or Air) is closed.

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

  2. Intel Smart Connect (ISCT)

    Intel Smart Connect (ISCT) is an Intel’s proprietary technology which is similar to Apple Power Nap. It works only on Windows PCs with certain Intel CPUs and Intel chipset manufactured starting from 2013 and requires BIOS support. Depending on the computer’s manufacturer and configuration, it might be enabled or disabled by default.

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

    • Advanced ­> PCH Configuration ­> Intel(R) Smart Connect Technology ­> ISCT Configuration

    • Advanced ­> Intel(R) Smart Connect Technology ­> Intel(R) Smart Connect Technology

    • Settings ­> Advanced ­> Intel(R) 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 Intel website.

    For more details on Intel Smart Connect (ISCT) support please contact your computer's manufacturer.

  3. Waking up over a local network

    On Mac:

    Most Macs support both Wake-on-Ethernet (WoL) and Wake-on-Wifi (WoWLAN) feature.

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

    To check if your Mac supports Wake-on-Wifi (WoWLAN) feature:

    • Open System Information.

      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 Mac Wake-on-Lan feature please visit this Apple KB article

    On PC

    In Windows Wake-on-LAN can be enabled by configuring 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 Wake-onLan feature is required on Windows computers.

  4. Bonjour Sleep Proxy

    Certain Apple devices such as Airport Express, Airport Extreme Base Station, Apple Time Capsule, Apple TVs and Macs running OS X 10.6 or later — can operate as a “helper” in local network to wake up a sleeping computer.

  5. Waking Up over Internet

    UPnP and NAT/PMP are similar technologies that enable waking up remote computer over internet This option will work for most home internet connections utilizing routers with NAT, and will not work for corporate networks.

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

    Most network routers made starting 2012 have UPnP enabled by default and will provide appropriate port forwarding from external IP address to local IP address. Also make sure the following port ranges are enabled:

    • UPNP: Allowed internal port range – 1­-65535

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

    Apple’s Airport/Time Capsule routers support NAT-PMP. To enable it, launch Airport Utility, go to NAT/Network and select “Enable NAT Port Mapping Protocol”.

Please visit KB122348 for more information about configuring NAT manually.
