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 Check

This option is available for the WAN and OPT interfaces. 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.

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 routing
