Chapter 13 Interfaces

LABEL

DESCRIPTION

 

Use Fixed IP

This option appears when Interface Properties is External or

 

Address

General. Select this if you want to specify the IP address, subnet

 

 

mask, and gateway manually.

 

 

 

 

IP Address

Enter the IP address for this interface.

 

 

 

 

Subnet Mask

Enter the subnet mask of this interface in dot decimal notation. The

 

 

subnet mask indicates what part of the IP address is the same for all

 

 

computers in the network.

 

 

 

 

Gateway

This option appears when Interface Properties is External or

 

 

General. Enter the IP address of the gateway. The ZyWALL sends

 

 

packets to the gateway when it does not know how to route the

 

 

packet to its destination. The gateway should be on the same network

 

 

as the interface.

 

 

 

 

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

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

 

Bandwidth

ZyWALL can send through the interface to the network. Allowed

 

 

values are 0 - 1048576.

 

 

 

 

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.

 

 

 

 

Connectivity

These fields appear when Interface Properties is External or

 

Check

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

Select this to turn on the connection check.

 

Connectivity

 

 

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.
