Port Mapping in Mountain Lion

There were some changes to the AirPort Utility in OS 10.8 Mountain Lion. Here are the steps to use when configuring your AirPort Extreme for remote time clock connectivity under Mountain Lion.

Open the Airport Utility. This is usually found in the Utilities folder in Applications and select your Airport Base Station.

Click the Network tab, under Port Settings click +.

Leave the description blank. Enter 56777 for both the public and private TCP ports (if the settings won't save, go ahead and enter 56778 for both the public and private UDP ports as well). Enter the IP address of the time clock server computer as the Private IP Address.

​Now you're ready to connect your time clock at another location or from home to the time clock server over the Internet.
