CONFIGURATION
What is Failover and What Is It Used For?
Failover is used for multiple redundant network connections to configure automatic activation of an alternative connection in the event of a primary connection failure. Another option is to use a primary connection and a backup connection, and configure Failover to automatically activate the backup connection in case of primary connection failure.
This configuration is typically employed when dealing with service providers that offer significantly different speeds, with the faster one designated as the primary connection and the secondary one serving as a backup until the primary connection is restored.
1. Access the equipment.
IP: 192.168.1.1.1 in the administration port (MGMT), you can access by any other IP that you have configured in your ports.
User: admin
Password: It is configured the first time you access.
Once inside the equipment interface select the following section Network -> Route/Load -> IP-Based Route. Click on add a default route.
2. In this section we will generate the static routes of the WAN and select which will be the primary and secondary. We fill in the following data as follows:
Outgoing interface: Select the WAN interface.
Gateway: IP of the Router or modem of that interface.
Route: Select if it is the main WAN or the secondary WAN.
Click on "Ok" to apply this record.
When configuring the 2 WANs it would look like this.
Go to the next section Network -> Line Escape in the "Line Traffic Escape" tab.
4. In this section, we will select the WAN interfaces that are configured and fill in the parameters for where we want to perform the communication ping when the primary connection goes down between the primary and secondary.**
Interface:We select our outgoing ports (WAN).
Ping Test:The IP of the Gateway of that interface's network for when the connection node goes offline or drops.
DNS Test:Provide a DNS for the search when the internet goes down.
TCP Test:Enter a URL or public IP for the search when the internet goes down. (This is not recommended as the website may go down without affecting the internet service).
Save your configuration.
With this, we have our failover configuration ready.
VERIFICATION
Disable or disconnect the primary WAN and wait for approximately 30 seconds to confirm that the internet connection has been restored with the secondary provider. Then, reconnect the primary service and verify that the traffic is routed through it.
