Table 27 WAN Backup Setup (continued)
LABEL | DESCRIPTION |
|
|
Timeout | Type the number of seconds (3 recommended) for your ZyXEL Device to wait for a |
| ping response from one of the IP addresses in the Check WAN IP Address field |
| before timing out the request. The WAN connection is considered "down" after the |
| ZyXEL Device times out the number of times specified in the Fail Tolerance field. |
| Use a higher value in this field if your network is busy or congested. |
Traffic Redirect | Traffic redirect forwards traffic to a backup gateway when the ZyXEL Device cannot |
| connect to the Internet. |
Active Traffic | Select this check box to have the ZyXEL Device use traffic redirect if the normal |
Redirect | WAN connection goes down. |
| Note: If you activate traffic redirect, you must configure at least one |
| Check WAN IP Address. |
Metric | This field sets this route's priority among the routes the ZyXEL Device uses. |
| The metric represents the "cost of transmission". A router determines the best route |
| for transmission by choosing a path with the lowest "cost". RIP routing uses hop |
| count as the measurement of cost, with a minimum of "1" for directly connected |
| networks. The number must be between "1" and "15"; a number greater than "15" |
| means the link is down. The smaller the number, the lower the "cost". |
Backup Gateway | Type the IP address of your backup gateway in dotted decimal notation. The ZyXEL |
| Device automatically forwards traffic to this IP address if the ZyXEL Device's |
| Internet connection terminates. |
Dial Backup |

|
Active Dial | Select this box to activate dial up backup. |
Backup |
|
Metric | This field sets this route's priority among the three routes the ZyXEL Device uses |
| (normal, traffic redirect and dial backup). Type a number (1 to 15) to set the priority |
| of the dial backup route for data transmission. The smaller the number, the higher |
| the priority. |
| If the three routes have the same metrics, the priority of the routes is as follows: |
| WAN, Traffic Redirect, Dial Backup. |
Port Speed | Select the speed of the connection between the dial backup port and the external |
| device. Available speeds are: 9600, 19200, 38400, 57600, 115200 or 230400 bps. |
User Name | Enter the user name for this backup connection. |

Primary Phone | Enter the phone number your modem should dial to create a connection. |
