AirPort Base Station Firmware 4.0.8 is an upgrade for the Snow (dual-Ethernet) base station. This firmware revision is not necessary for the Graphite base station nor the AirPort Extreme Base Station. It is recommended that you use AirPort 2.1.1 or later software with this base station firmware release. The update fixes an incompatibility with some customers unable to maintain an Internet connection using BellSouth via a DSL and/or Dial-up connection, provides base station support for DSL users with the Telia ISP in Sweden, and expands the number of Access Control List entries and the number of port mapping entries to from 10 to 20.
