Metric

This option appears when

Interface Properties

is

External

or

General

. Enter the priority of the gateway (if any) on this interface.

The ZyWALL decides which gateway to use based on this priority. The

lower the number, the higher the priority. If two or more gateways

have the same priority, the ZyWALL uses the one that was configured

first.

Interface

Parameters

Egress

Bandwidth

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.

Ingress

Bandwidth

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.

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.

Connectivity

Check

These fields appear when

Interface Properties

is

External

or

General

.

The interface can regularly check the connection to the gateway you

specified to make sure it is still available. You specify how often the

interface checks the connection, how long to wait for a response

before the attempt is a failure, and how many consecutive failures are

required before the ZyWALL stops routing to the gateway. The

ZyWALL resumes routing to the gateway the first time the gateway

passes the connectivity check.

Enable

Connectivity

Check

Select this to turn on the connection check.

Check Method

Select the method that the gateway allows.

Select

icmp

to have the ZyWALL regularly ping the gateway you

specify to make sure it is still available.

Select

tcp

to have the ZyWALL regularly perform a TCP handshake

with the gateway you specify to make sure it is still available.

Check Period

Enter the number of seconds between connection check attempts.

Check Timeout

Enter the number of seconds to wait for a response before the

attempt is a failure.

Check Fail

Tolerance

Enter the number of consecutive failures before the ZyWALL stops

routing through the gateway.

Check Default

Gateway

Select this to use the default gateway for the connectivity check.

Check this

address

Select this to specify a domain name or IP address for the

connectivity check. Enter that domain name or IP address in the field

next to it.

Check Port

This field only displays when you set the

Check Method

to

tcp

.

Specify the port number to use for a TCP connectivity check.

DHCP Setting

These fields appear when

Interface Properties

is

Internal

or

General

.

DHCP

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

.

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

Address

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, use the

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.

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

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.

First DNS

Server, Second

DNS Server,

Third DNS

Server

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.

First WINS

Server, Second

WINS Server

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.

Lease time

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.

Enable IP/MAC

Binding

Select this option to have this interface enforce links between specific

IP addresses and specific MAC addresses. This stops anyone else from

manually using a bound IP address on another device connected to

this interface. Use this to make use only the intended users get to use

specific IP addresses.

Enable Logs

for IP/MAC

Binding

Violation

Select this option to have the ZyWALL generate a log if a device

connected to this interface attempts to use an IP address that is

bound to another device’s MAC address.

Static DHCP

Table

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

.

OSPF Setting

See

Section 14.3 on page 299

for more information about OSPF.

Area

Select the area in which this interface belongs. Select

None

to disable

OSPF in this interface.

Priority

Enter the priority (between 0 and 255) of this interface when the area

is looking for a Designated Router (DR) or Backup Designated Router

(BDR). The highest-priority interface identifies the DR, and the

second-highest-priority interface identifies the BDR. Set the priority

to zero if the interface can not be the DR or BDR.

Link Cost

Enter the cost (between 1 and 65,535) to route packets through this

interface.

Passive

Interface

Select this to stop forwarding OSPF routing information from the

selected interface. As a result, this interface only receives routing

information.

exchange OSPF routing information with peer border routers, you

must use the same authentication method that they use. Choices are:

Same-as-Area

- use the default authentication method in the area
