How to block Counter Strike using Airport Extreme

By default, the AirPort Extreme blocks all incoming traffic, but cannot block outbound ports directly. One workaround to "discourage" access to particular Internet games is to enable Port Mapping to map the game's required ports to a non-existent device on your local network.

As an example, let's say you need to block ports 2000 thru 2005. In addition, the IP address range of the computers on your network are: 10.0.1.2 thru 10.0.1.100. You can then configure Port Mapping to map these ports to a device with an IP address of 10.0.1.200. Since this device does not actually exist, Internet traffic coming into your network will be "lost" and the game should be unplayable.

The "Service" option is only to provide you with a set of pre-defined port settings for the most common types of Internet traffic. You can safely ignore this particular setting and just enter the appropriate UDP & TCP port values for both the Public and Private entries. Also be sure to assign a "non-existent" Private IP Address value. Remember you want all inbound traffic to be sent (mapped) to a device that doesn't actually exist.

Yes, these would be the Public ones. I suggest using the same ports for the Private ones. Since there is no real device, it shouldn't matter.

You're very welcome! I hope this solves the problem for you. Please post back after giving it a try as I would be curious as to the results.
