Do ADmitMac and DAVE work with AirPort?

Yes. ADmitMac and DAVE can work with AirPort. The reason some users have trouble connecting with AirPort is because of the way some routers use NAT (Network Address Translation) to share an IP address.

NAT is what some routers use to assign a list of private TCP/IP addresses to computers on an internal network while those same computers share a single TCP/IP address to access an external network (such as the Internet). A fortunate side effect is that the TCP/IP address of the computers on the internal network are masked from the computers on the external network. This means computers on the external network (or the Internet) are not able to access computers on the internal network, providing security. If you have more than one router on your network providing NAT services, you may experience connection problems with your local network.

There are several ways to configure your network with AirPort, below are two that should work fine when using DAVE or ADmitMac.

1.
If the AirPort is the only router on the network, you should configure the AirPort base station to "Distribute IP addresses", and you should also configure TCP/IP on your Macintosh to use DHCP to obtain an IP address automatically.

To configure your AirPort base station, you should use the AirPort Admin Utility on the Macintosh. In Mac OS 9.x and below, this can be found in the hard_drive/applications/AirPort. In Mac OS X it's located in hard_drive/applications/utilities.

Once you open this, highlight the appropriate AirPort base station and click on the 'Configure' button (you will be prompted for the AirPort base station password so make sure you have this). This will open a new window with several tabs, select the 'Network' tab. Here you will see the option to check "Distribute IP addresses". Once you have done this, click on the 'update' and then the 'restart' buttons in this window.

To configure TCP/IP in Mac OS 9.x and below, go under Control Panels and select the "TCP/IP" control panel. In Mac OS X, go into "System Preferences" and select the "Network" preference.

2.
The second possible manner of configuring AirPort would be if there is already a router on the network that is distributing IP addresses for the network, and your Macintosh was already set to use DHCP to obtain an IP address from this router. In this case, you would configure the AirPort base station as a bridge so that it does not distribute its own set of IP addresses. If you do not do this, you may experience connection problems with your local network.

To configure your AirPort base station as a bridge so that it does not distribute its own set of IP addresses, you will use the AirPort Admin Utility mentioned before but this time uncheck the option to "Distribute IP addresses". Once you have done this, click on the 'update' and then the 'restart' buttons in this window.
