DESCRIPTION

Egress

Enter the maximum amount of traffic, in kilobits per second, the ZyWALL can

Bandwidth

send through the interface to the network. Allowed values are 0 - 1048576. This

 

setting is used in WAN load balancing and bandwidth management.

 

 

Ingress

This is reserved for future use.

Bandwidth

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.

 

 

MTU

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.

 

 

DHCP Settings

 

 

 

DHCP

Select what type of DHCP service the ZyWALL provides to the wireless 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.

 

 

Relay Server 1

Enter the IP address of a DHCP server for the network.

 

 

Relay Server 2

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.

 

 

IP Pool Start

Enter the IP address from which the ZyWALL begins allocating IP addresses.

Address

If this field is blank, the ZyWALL assigns every IP address allowed by the

 

interface’s IP address, subnet mask, and pool size; 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 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 network

Server

can use. The ZyWALL provides these IP addresses to DHCP clients. Use one of

Second DNS

the following ways to specify these IP addresses.

Server

Custom Defined - enter a static IP address.

Third DNS

From ISP - select the DNS server that another interface received from its DHCP

Server

 

server.

 

ZyWALL - the ZyWALL uses the IP address of this interface and works as a DNS

 

relay.

 

 

First WINS

Type the IP address of the WINS (Windows Internet Naming Service) server that

Server, Second

you want to send to the DHCP clients. The WINS server keeps a mapping table of

WINS Server

the computer names on your network and the IP addresses that they are currently

 

using.
