Three Methods:Set Static IP AddressEnable UPnPForward Ports

When you connect the MagicJack device to your Mac, you can make free phone calls to any phone number in the United States and Canada or to another MagicJack device anywhere in the world. If you have a gateway or router with a firewall on your network, you need to enable universal plug and play so the MagicJack can request ports from your router. If your router doesn't support UPnP, you must forward ports 5060 and 5070 for the UDP protocol to your Mac's IP address. Establish a fixed IP address for your Mac first if it doesn't already have one.

Method 1 of 3: Set Static IP Address

  1. 1
    Pull down "System Preferences" from the Apple menu, and then select the "Network" preference pane. Note your current IP address, such as "," for example.
  2. 2
    Click "Advanced" and select the "TCP/IP" tab. Note the address labeled "Router," and then choose "Cancel" to exit the Advanced setup.
  3. 3
    Add or subtract 52 from your current IP address, but keep the last number of the address between 2 and 253. For example, if your current address is "," subtract 52 from 100 to get 48, which is between 2 and 253. Assign a static address to your Mac of ""
  4. 4
    Select "Edit Locations..." from the Location selector box. Enter a name for a new location -- such as "MagicJack," for example -- and choose "Done."
  5. 5
    Select "Manually" to configure your IP address. Type an IP address for your Mac, and then type "" for the subnet mask. Enter the address of your router you recorded in Step 2. Type the address for your router a second time for the DNS Server. Leave the Search Domains blank, and then choose "Apply."

Method 2 of 3: Enable UPnP

  1. 1
    Open Safari and type the address of your router into the address bar. Enter the username and password for your router, and log in to access its settings.
  2. 2
    Select the Advanced Settings menu or a menu selection for Firewall or Port Forwarding.
  3. 3
    Locate a setting labeled UPnP, and enable it if it's not activated. Proceed to the next section if you don't find a UPnP option on your router. Otherwise, save your changes, wait for your router to reboot and test your MagicJack.

Method 3 of 3: Forward Ports

  1. 1
    Locate the Port Forwarding options, and forward two ports. Enter the IP address of your Mac. Enter "5060" as the first port to forward in the range, and enter it again as the last port to forward in the range. Select "UDP" for the protocol.
  2. 2
    Enter your Mac's IP address again. Type "5070" for the beginning and ending port numbers in the range, and then select "UDP" as the protocol.
  3. 3
    Save your changes and wait for your router to reboot. Test your MagicJack from your Mac.
