DESCRIPTION
This is the final network prefix combined by the selected delegated prefix and the
suffix.
Note: This field displays the combined address after you click OK and reopen this
screen.
Enter the maximum amount of traffic, in kilobits per second, the ZyWALL can send
through the interface to the network. Allowed values are 0 - 1048576.
This is reserved for future use.
Enter the maximum amount of traffic, in kilobits per second, the ZyWALL can receive
from the network through the interface. Allowed values are 0 - 1048576.
Maximum Transmission Unit. Type the maximum size of each data packet, in bytes,
that can move through this interface. If a larger packet arrives, the ZyWALL divides it
into smaller fragments. Allowed values are 576 - 1500. Usually, this value is 1500.
Select what type of DHCP service the ZyWALL provides to the network. Choices are:
None - the ZyWALL does not provide any DHCP services. There is already a DHCP
server on the network.
DHCP Relay - the ZyWALL routes DHCP requests to one or more DHCP servers you
specify. The DHCP server(s) may be on another network.
DHCP Server - the ZyWALL assigns IP addresses and provides subnet mask, gateway,
and DNS server information to the network. The ZyWALL is the DHCP server for the
network.
These fields appear if the ZyWALL is a DHCP Relay.
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 Add Static DHCP.
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.
