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. This setting is
used in WAN load balancing and bandwidth management.
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
This section is available if you are configuring a GRE tunnel.
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.

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
