LABEL	DESCRIPTION
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 ZyWALL can assign every IP address allowed
	by the interface’s IP address, subnet mask, and IP Pool Start
	Address; except for the first address (network address), last address
	(broadcast address) and the interface’s IP address.
First DNS	Specify the IP addresses of a maximum of three DNS servers that the
Server	network can use. The ZyWALL provides these IP addresses to DHCP
Second DNS	clients. Use one of the following ways to specify these IP addresses.
Server
Third DNS	Custom Defined - enter a static IP address.

	addresses are valid.
