Enabling NAT on your AirPort Network
NAT-PMP or UPnP must be enabled on the router you plan to use with the computer you plan to access. I can’t tell you how to enable it on every router out there, but I can explain how to do it with an AirPort Extreme base station—even if you have the old "flying saucer" version of this device, like I do.
- Open the AirPort Utility in your Utilities folder.
- In the AirPort Utility window, select the AirPort base station you want
to configure (see Figure 5).
Figure 5 Select your AirPort base station.
- Click the Manual Setup button.
- If necessary, provide a password to access the AirPort’s settings.
- Click the Internet button in the window’s toolbar. Then click the
NAT button near the top of the window to display the NAT (see Figure 6).

- If necessary, turn on the check box labeled Enabled NAT Port Mapping Protocol and click the Update button. Wait while the base station is updated and it restarts.
- Quit the AirPort Utility.
