DHCP 

If set to Server, your ZyAIR can assign IP addresses, an IP default 
gateway and DNS servers to Windows 95, Windows NT and other 
systems that support the DHCP client.   
If set to None, the DHCP server will be disabled.  
If set to Relay, the ZyAIR acts as a surrogate DHCP server and relays 
DHCP requests and responses between the remote server and the 
clients.  Enter the IP address of the actual, remote DHCP server in the 
Remote DHCP Server in this case. 

When DHCP is used, the following items need to be set:
