If the computer you are attempting to connect to via Back to My Mac is connected to the Internet through an AirPort Extreme Gigabit Ethernet base station, the connection may not be successful.
This can occur even if you have enabled NAT-PMP.
When AirPort Utility 5.1 or later is opened, it automatically checks all accessible Time Capsule, AirPort Extreme and AirPort Express base stations' firmware. If a newer (later) firmware version is available from Apple, you'll be notified and presented with onscreen instructions to download and install the base station(s) firmware.
AirPort Utility is located in the Utilities folder inside the Applications folder on a computer using Mac OS X, and (on a computer using Windows) in Start > All Programs > AirPort.
Your USB printer may work the way you expect it to when connected to your computer, but not when it's connected to your AirPort Base Station or Time Capsule for Printer Sharing.
This document describes the security content of AirPort Extreme Base Station Firmware 7.3.1, which can be downloaded and installed via Software Update preferences, or from Apple Downloads.

Back to My Mac (BTMM) is a Mac OS X 10.5 Leopard feature that makes it easy to automatically connect to your other computers over the Internet. It requires the use of either an AirPort base station with NAT-PMP (NAT Port Mapping Protocol), or a third-party Internet router with UPnP (Universal Plug and Play) technology. For more information on setting up Back to My Mac, see this article. Note: For best compatibility with Back to My Mac you should: Mac OS X 10.5.2 or later: You can use Software Update to download and install available Leopard updates.
Issue or symptom
When connected to a wireless network using AirPort and using multiple Bluetooth devices, your AirPort may have a slightly slower transfer rate.
Products affected
MacBook Air
Solution
To improve MacBook Air's Airport connectivity and signal performance when using multiple Bluetooth devices, try the following:
Connect to a 5 GHz 802.11 wireless network instead of a 2.4 GHz 802.11 wireless network.
If using an AirPort base station, use the AirPort Admin Utility to select a different channel. If using a third-party wireless network, consult the documentation that came with the router device to determine how to
You should use Cisco's VPN client software to establish a Cisco VPN connection via an AirPort Extreme base station. Note: In the Cisco VPN client preferences, make sure the "NAT-T" option is enabled.
Note: Some corporate firewall configurations may cause issues with the Cisco VPN software.
Please contact AppleCare support if you are unable to contact a Cisco VPN server via Cisco VPN client software and an AirPort Extreme base station.

Typically, when a USB disk is connected to an AirPort Extreme Base Station (802.11n), it will automatically become available to users of the network. However, if that option is disabled in AirPort Disk Utility (Mac OS X) or AirPort Disks (Windows), or the network user declines, it can still be accessed using any of appropriate steps below. By default, a user can access the AirPort Extreme Base Station (802.11n) over IP by entering the IP address 10.0.1.1.
If you are unsure of the IP address of your AirPort Extreme (802.11n), use AirPort Utility (Mac OS X)

An AirPort Extreme (802.11n) base station can be configured to forward multiple ports from the Internet to inside your NAT/network.
Enter the port XXX-YYY as shown below. Note that there are no spaces in the port range.
After you have installed and updated AirPort Utility, the application "AirPort Admin Utility" is renamed to "AirPort Admin Utility for Graphite and Snow".
AirPort Admin Utility for Graphic and Snow can be used to configure earlier AirPort base stations, but not to configure an AirPort Extreme (802.11n) base station. If you have one of these older base stations, you can still configure it using the AirPort Admin Utility for Graphite and Snow.

With AirPort Utility and Mac OS X, you can use an Access Control List (ACL) to restrict access to your AirPort base station network to specific computers that you specify. You can export an Access Control list as a text file with AirPort Admin Utility, then use AirPort Utility to upload the list to a new AirPort Extreme (802.11n) base station.
To import an existing Access Control list:
Open AirPort Utility in Mac OS X and select the base station you will be sending the list to.
Configure the base station manually by choosing Manual Setup from the Base Station menu or
