DESCRIPTION
Enter the IP address of a DHCP server for the network.
This field is optional. Enter the IP address of another DHCP server for
the network.
These fields appear if the ZyWALL is a DHCP Server.
Enter the IP address from which the ZyWALL begins allocating IP
addresses. If you want to assign a static IP address to a specific
computer, click Edit 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.
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.
Specify the IP addresses up to three DNS servers for the DHCP clients
to use. Use one of the following ways to specify these IP addresses.
Custom Defined - enter a static IP address.
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.
Type the IP address of the WINS (Windows Internet Naming Service)
server that you want to send to the DHCP clients. The WINS server
keeps a mapping table of the computer names on your network and
the IP addresses that they are currently using.
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.
Click this to configure static IP addresses for the ZyWALL to assign to
computers connected to this interface.
Click this to save your changes back to the device.
Click this to exit this screen without saving.
