LABEL

DESCRIPTION

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.

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

Enter the number of consecutive failures before the ZyWALL stops

Tolerance

routing through the gateway.

 

 

Check Default

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

Gateway

 

 

 

Check this

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

address

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

 

next to it.
