Health Check
Use this field to select the type of connection validation to perform. The Twin WAN Gateway supports the following Health Check options:
|
When enabled, the Twin WAN Gateway sends ICMP echo requests to the gateway of each connection. If Alive Indicator is specified then it will be used instead. |
|
When enabled, the Twin WAN Gateway retrieves html pages in order to verify connectivity to the internet. Use only if ISP does not support ICMP packets. |
|
When enabled, the Twin WAN Gateway monitors inbound and outbound traffic on both WAN ports and to verify there is connectivity. If the connections are idle, ICMP or HTTP health check methods will be utilized. |
Alive Indicator
This is the IP address used to check if the WAN connection is operational. When using HTTP, put in a valid IP address of a web server. When this field is blank, the IP address of your ISP is used.
Note: This is not used for PPPoE connections.
MTU
The Maximum Transmission Unit is used when determining the packet size to be used on the WAN interface. Normally, this does not need to be changed, but if your ISP advises you to use a particular MTU, enter it here.
PPPoE / PPTP Connection Options |
Auto Dialup
When Enabled, a connection will be established whenever outgoing WAN traffic is detected. If this option is not Enabled, you must establish a connection manually.
Auto Disconnect
This determines when an idle connection will be terminated. Enter the required time period.
Echo Time
This determines how often an Echo request is sent to the PPPoE server. The Echo request is used to determine if the connection is still valid. The default value is 30 seconds.
Echo Retry
This paramater indicates the number of times an Echo request will be sent if there is no response to the first request. The default value is 3 times.
Transparent Bridge Option |
Bridge Mode
When set to Enable, this WAN port does not use NAT & Load Balance function when LAN/WAN IP have the real IP addresses on the same network segment.
|
When a WAN port connection becomes disconnected, all traffic from the bridged device will not failover to the other WAN port. |
|
When the WAN port connection becomes disconnected, all traffic from the briddged device will failover to the other WAN port. |
|
This will mix real and private IP’s on the LAN side doing the load balancing. |
