AirPort 1.3 software
The AirPort Base Station can accommodate a DHCP Client ID while providing Network Address Translation (NAT). This is one advantage of updating to AirPort 1.3.
If your network or Internet service provider requires the DHCP Client ID, follow these steps to add it:
1. Open the AirPort Admin Utility.
2. Click the Internet tab.
3. Choose Ethernet from the Connect Using pop-up menu.
4. Choose DHCP from the Configure TCP/IP pop-up menu. The DHCP Client ID field becomes available.
5. Enter the DHCP Client ID in the field.
6. Click Update.
AirPort 1.2 and earlier software
Though the AirPort Base Station does not accommodate DHCP Client ID, there are two solutions available. In either solution, the DHCP Client ID would be entered in the individual TCP/IP control panels of the computers that connect wirelessly to the AirPort Base Station.
Important: You should update your AirPort Base Station to AirPort 1.3 software. The presented solutions, while valid, require the dedication of time and resources that are unnecessary if you update your software. These solutions are presented for your information only.
Solutions for DHCP Client ID with AirPort 1.2 and earlier
An IP Address for Each Computer 1. Obtain additional DHCP leases from your Internet Service Provider or network administrator for each computer that will connect to the base station. A DHCP lease is the ability for one computer to obtain the IP address necessary to connect to the Internet. If your provider or network uses static IP addresses instead of DHCP service, obtain additional static IP addresses.
2. Set up the AirPort Base Station as a bridge only.
Add a Router 1. Set up a separate router on the network for DHCP and NAT services. Routers come in many sizes, from industrial strength to table top. A computer with two Ethernet interfaces and routing software may also serve the same purpose.
2. Set up the AirPort Base Station as a bridge only.
Important: Bridging may adversely affect other network services in certain environments. If you have a cable modem, you should not use the AirPort Base Station for bridging combined with NAT (network address translation) and DHCP services. NAT and DHCP services may be run on a separate router.
Note: Computers that are set up as AirPort software base stations do not have a bridging feature.

Note: Wireless Internet access requires an Internet service provider (fees may apply) and AirPort (or AirPort-compatible) wireless Ethernet card and base station. Some ISPs are not compatible with AirPort. For more information, see technical document 106590: "
