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 - 1492. Usually, this value is 1492.

Connectivity 
Check

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.

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.

routing through the gateway.

Check Default 

Gateway

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

This field only displays when you set the Check Method to tcp. 
Specify the port number to use for a TCP connectivity check.
