Chapter 13 Interfaces Table 59 Configuration > Network > Interface > Ethernet > Edit (continued) LABEL DESCRIPTION Use Fixed IP Address This option appears when Interface Properties is External or General. Select this if you want to specify the IP address, subnet mask, and gateway manually. IP Address Enter the IP address for this interface. Subnet Mask Enter the subnet mask of this interface in dot decimal notation. The subnet mask indicates what part of the IP address is the same for all computers in the network. Gateway This option appears when Interface Properties is External or General. Enter the IP address of the gateway. The ZyWALL sends packets to the gateway when it does not know how to route the packet to its destination. The gateway should be on the same network as the interface. 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 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 - 1500. Usually, this value is 1500. Connectivity Check These fields appear when Interface Properties is External or General. Enable Connectivity Check Check Method 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 this to turn on the connection check. 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. ZyWALL USG 2000 User's Guide 287
