DESCRIPTION
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.
Specify the IP addresses of a maximum of three DNS servers that the
network can use. The ZyWALL provides these IP addresses to DHCP
clients. 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 ZyWALL uses the IP address of this interface and 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.
Configure a list of static IP addresses the ZyWALL assigns to
computers connected to the interface. Otherwise, the ZyWALL assigns
an IP address dynamically using the interface's IP Pool Start
Address and Pool Size.
Click this to create a new entry.
Select an entry and click this to be able to modify it.
Select an entry and click this to delete it.
This field is a sequential value, and it is not associated with a specific
entry.
Enter the IP address to assign to a device with this entry's MAC
address.
Enter the MAC address to which to assign this entry's IP address.
Enter a description to help identify this static DHCP entry. You can use
alphanumeric and ()+/:=?!*#@$_%- characters, and it can be up to 60
characters long.
