LABEL	DESCRIPTION
IP Pool Start	Enter the IP address from which the ZyWALL begins allocating IP addresses. If you
Address	want to assign a static IP address to a specific computer, use the Static DHCP Table.
	If this field is blank, the Pool Size must also be blank. In this case, the ZyWALL can
	assign every IP address allowed by the interface’s IP address and subnet mask, except
	for the first address (network address), last address (broadcast address) and the
	interface’s IP address.
Pool Size	Enter the number of IP addresses to allocate. This number must be at least one and is
	limited by the interface’s Subnet Mask. For example, if the Subnet Mask is
	255.255.255.0 and IP Pool Start Address is 10.10.10.10, the ZyWALL can allocate
	10.10.10.10 to 10.10.10.254, or 245 IP addresses.
	If this field is blank, the IP Pool Start Address must also be blank. In this case, the
	ZyWALL can assign every IP address allowed by the interface’s IP address and subnet
	mask, except for the first address (network address), last address (broadcast address)
	and the interface’s IP address.
First DNS	Specify the IP addresses up to three DNS servers for the DHCP clients to use. Use one
Server, Second	of the following ways to specify these IP addresses.
DNS Server,
Third DNS	Custom Defined - enter a static IP address.
Server
	From ISP - select the DNS server that another interface received from its DHCP
	server.
	ZyWALL - the DHCP clients use the IP address of this interface and the ZyWALL works
	as a DNS relay.
First WINS	Type the IP address of the WINS (Windows Internet Naming Service) server that you
Server, Second	want to send to the DHCP clients. The WINS server keeps a mapping table of the
WINS Server	computer names on your network and the IP addresses that they are currently using.
Default Router	If you set this interface to DHCP Server, you can select to use either the interface’s IP
	address or another IP address as the default router. This default router will become the
	DHCP clients’ default gateway.
	To use another IP address as the default router, select Custom Defined and enter the
	IP address.
Lease time	Specify how long each computer can use the information (especially the IP address)
	before it has to request the information again. Choices are:
	infinite - select this if IP addresses never expire.
	days, hours, and minutes - select this to enter how long IP addresses are valid.
Extended	This table is available if you selected DHCP server.
Options	Configure this table if you want to send more information to DHCP clients through
	DHCP packets.
Add	Click this to create an entry in this table. See Section 7.3.4 on page 124.
