What Is Mikrotik Router Policy Routing 2 WAN Fail-over Configuration?

Mikrotik Router Policy Routing 2 WAN Fail-over Configuration is a configuration that allows network administrators to establish policies that govern what happens in the event of a failure of the primary WAN link.

Step-by-Step Guide to Setting Up Mikrotik Router Policy Routing 2 WAN Fail-over Configuration

Step 1: Connect Your Second WAN Connection

The first thing you need to do to set up Mikrotik Router Policy Routing 2 WAN Fail-over Configuration is to connect the second WAN connection. This connection should come from a secondary ISP or another connection that provides internet connectivity. Once you have connected the second WAN connection, proceed to the next step.

Step 2: Configure Both WAN Connections

The next step is to configure both your primary and secondary WAN connections. You need to ensure that each connection has its own static IP address and that they are both properly configured for internet connectivity. Once you have configured both WAN connections, you can proceed to the next step.

Step 3: Set Up the Policy Routes

With your WAN connections properly configured, the next step is to set up the policy routes. This is done by navigating to the IP > Firewall > Mangle tab on your router. Here, you will set up the following rules:

• Rule 1: This rule will match all traffic that should be sent through the primary WAN connection. The action for this rule should be set to passthrough, and the routing mark set to "primary".
• Rule 2: This rule will match all traffic that should be sent through the secondary WAN connection. The action for this rule should be set to passthrough, and the routing mark set to "secondary".

Once you have successfully set up these rules, you can proceed to the next step.

Step 4: Set Up the Fail-over Script

The next step in setting up Mikrotik Router Policy Routing 2 WAN Fail-over Configuration is to set up the fail-over script. This script should be set up to automatically activate the secondary WAN connection in the event of a failure of the primary WAN connection. Here's how to set up the fail-over script:

1. Navigate to the System > Scripts tab on your router.
2. Click on the Add button to add a new script.
3. Enter a name for the script, such as "failover".
4. In the Source field, enter the following command: /ip route set [find comment="failover"] distance=1
5. Click on OK to save the script.

Once you have successfully set up the fail-over script, you can proceed to the final step.

Step 5: Set Up the Fail-over Check

The final step in setting up Mikrotik Router Policy Routing 2 WAN Fail-over Configuration is to set up the fail-over check. This check should be set up to test the primary WAN connection for a failure and switch to the secondary WAN connection automatically. Here's how to set up the fail-over check:

1. Navigate to the System > Scheduler tab on your router.
2. Click on the Add button to add a new scheduler.
3. Enter a name for the scheduler, such as "failover check".
4. In the Interval field, enter a value that corresponds to the frequency of the check (e.g. 5 minutes).
5. In the On Event field, enter the following command: /ping 8.8.8.8 interval=1s count=3 comment=failover || /ip route set [find comment="failover"] distance=2
6. Click on OK to save the scheduler.

Once you have successfully set up the fail-over check, your Mikrotik Router Policy Routing 2 WAN Fail-over Configuration is complete!
