LABEL	DESCRIPTION
Interface
Parameters
Egress	Enter the maximum amount of traffic, in kilobits per second, the ZyWALL can send
Bandwidth	through the interface to the network. Allowed values are 0 - 1048576. This setting is
	used in WAN load balancing and bandwidth management.
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 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.
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.
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 through the
Tolerance	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 connectivity check. Enter
address	that domain name or IP address in the field next to it.
Check Port	This field displays when you set the Check Method to tcp. Specify the port number to
	use for a TCP connectivity check.
