Failover across multiple WAN connections

Now, pfSense has been configured for load balancing and implicit failover. Let's proceed and verify this configuration further.

Let's take the verification one step further. Instead of disabling a WAN connection, let's try to disable each of the gateways and observe the effects:

1. Click System tab on the toolbar and select Routing. Click the Gateway Groups tab:

Both have the Priority set to Tier 1, which indicates that pfSense is currently working as a load balancer, which inherently also provides failover.

2. Click the Gateways tab and let's disable the first link, which is WAN1-DHCP:

3. Click the Edit icon to its left. Scroll down to the field Force State. Select the Mark Gateway as Down checkbox:

 

4. Click Save. Click Apply Changes. Go back to the client machine and see if it is getting a response. You will see that there isn't any drop in the connectivity as the traffic is being routed automatically through the second ISP, that is, the WAN2 interface.
5. Go back...
