Chapter 9 Interfaces Table 119 Configuration > Network > Interface > Bridge > Add / Edit (continued) LABEL DESCRIPTION Connectivity Check 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 Zyxel Device stops routing to the gateway. The Zyxel Device 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 Zyxel Device regularly ping the gateway you specify to make sure it is still available. Check Period Check Timeout Check Fail Tolerance Check Default Gateway Check this address Check Port Check these addresses Probe Succeeds When Select tcp to have the Zyxel Device regularly perform a TCP handshake with the gateway you specify to make sure it is still available. Enter the number of seconds between connection check attempts. Enter the number of seconds to wait for a response before the attempt is a failure. Enter the number of consecutive failures before the Zyxel Device stops routing through the gateway. Select this to use the default gateway for the connectivity check. Select this to specify a domain name or IP address for the connectivity check. Enter that domain name or IP address in the field next to it. This field only displays when you set the Check Method to tcp. Specify the port number to use for a TCP connectivity check. Type one or two domain names or IP addresses for the connectivity check. This field applies when you specify two domain names or IP addresses for the connectivity check. Select any one if you want the check to pass if at least one of the domain names or IP addresses responds. Select all if you want the check to pass only if both domain names or IP addresses respond. Proxy ARP Proxy ARP is available for external or general interfaces on the Zyxel Device. See Section on page 254 for more information on Proxy ARP. Enable Proxy ARP Select this to allow the Zyxel Device to answer external interface ARP requests on behalf of a device on its internal interface. Interfaces supported are: Add • Ethernet • VLAN • Bridge See Section 9.4.2 on page 263 for more information. Click Add to create an IPv4 Address, an IPv4 CIDR (for example, 192.168.1.1/24) or an IPv4 Range (for example, 192.168.1.2-192.168.1.100) as the target IP address. The Zyxel Device answers external ARP requests only if they match one of these inputted target IP addresses. For example, if the IPv4 Address is 192.168.1.5, then the Zyxel Device will answer ARP requests coming from the WAN only if it contains 192.168.1.5 as the target IP address. Select an existing entry and click Remove to delete that entry. ZyWALL ATP Series User's Guide 317
