154 Appendix B Configuring an Internet Router
The server can configure port mapping automatically on an AirPort Base Station that
has the default password (public). If the base station has a different password, you can
enter it while setting up the server locally, and the server will be able to configure port
mapping on the base station. If you set up your server remotely, it will be able to
configure port mapping automatically as long as your base station uses the default
password. However, the default password is fairly well known, and using it will
compromise the security of your wireless network.
Automatic configuration of an AirPort Base Station requires that the setting IPv6 Mode
be set to Tunnel in the AirPort Utility application (located in /Applications/Utilities/).
The AirPort Base Station must be set up to share an Internet connection with
computers connected to it by Ethernet.
Only standard and workgroup configurations of Leopard Server configure an AirPort
Base Station automatically. An advanced configuration of Leopard Server leaves port
mapping to the administrator.
Note: Users who have accounts on your server should make a VPN connection to your
server to get secure remote access to all services over the Internet. Setting up port
forwarding, whether automatically on an AirPort Extreme or manually as described
next, makes only some of your server’s services available on the Internet.
