Table 32 WAN General
LABEL | DESCRIPTION | |
|
| |
Active/Passive | Select the Active/Passive (fail over) operation mode to have the ZyWALL use the | |
(Fail Over) Mode | second highest priority WAN port as a back up. This means that the ZyWALL will | |
| normally use the highest priority (primary) WAN port (depending on the priorities | |
| you configure in the Route Priority fields). The ZyWALL will switch to the | |
| secondary (second highest priority) WAN port when the primary WAN port's | |
| connection fails. | |
Fall Back to | This field determines the action the ZyWALL takes after the primary WAN port fails | |
Primary WAN | and the ZyWALL starts using the secondary WAN port. | |
When Possible | Select this check box to have the ZyWALL change back to using the primary WAN | |
| port when the ZyWALL can connect through the primary WAN port again. | |
| Clear this check box to have the ZyWALL continue using the secondary WAN port, | |
| even after the ZyWALL can connect through the primary WAN port again. The | |
| ZyWALL continues to use the secondary WAN port until it's connection fails (at | |
| which time it will change back to using the primary WAN port if its connection is up. | |
Active/Active | Select Active/Active Mode to have the ZyWALL use both of the WAN ports at the | |
Mode | same time and allow you to enable load balancing. | |
Load Balancing | Select Least Load First, Weighted Round Robin or Spillover to activate load | |
Algorithm | balancing and set the related fields. Otherwise, select None. | |
| Refer to Section 7.7 on page 133 for load balancing configuration. | |

| |
Route Priority |
| |
|
| |
WAN1 | The default WAN connection is "1' as your broadband connection via the WAN port | |
WAN2 | should always be your preferred method of accessing the WAN. The ZyWALL | |
switches from WAN port 1 to WAN port 2 if WAN port 1's connection fails and then | ||
Traffic Redirect | ||
back to WAN port 1 when WAN port 1's connection comes back up. The default | ||
Dial Backup | ||
priority of the routes is WAN 1, WAN 2, Traffic Redirect and then Dial Backup: | ||
| You have three choices for an auxiliary connection (WAN 2, Traffic Redirect and | |
| Dial Backup) in the event that your regular WAN connection goes down. If Dial | |
| Backup is preferred to Traffic Redirect, then type "14" in the Dial Backup Priority | |
| (metric) field (and leave the Traffic Redirect Priority (metric) at the default of | |
| "15"). | |
| The Dial Backup field is available only when you enable the corresponding dial | |
| backup feature in the Dial Backup screen. | |
Connectivity |
| |
Check |
| |
Check Period | The ZyWALL tests a WAN connection by periodically sending a ping to either the | |
| default gateway or the address in the Ping this Address field. | |
| Type a number of seconds (5 to 300) to set the time interval between checks. Allow | |
| more time if your destination IP address handles lots of traffic. | |
Check Timeout | Type the number of seconds (1 to 10) for your ZyWALL to wait for a response to the | |
| ping before considering the check to have failed. This setting must be less than the | |
| Check Period. Use a higher value in this field if your network is busy or congested. | |
Check Fail | Type how many WAN connection checks can fail | |
Tolerance | considered "down" (not connected). The ZyWALL still checks a "down" connection | |
| to detect if it reconnects. |
