Load balancing and failover across multiple WAN connections
Now, let's go ahead and configure pfSense to act as a load balancer across multiple WAN connections:
- Let's switch to the pfSense server. Here we are at the command-line dashboard for pfSense:

You can see here that we have configured two WAN
connections. The first WAN
interface is em0
and the WAN2
interface is em2
. Both of them have different IPs. The LAN1
interface is em1
. Basically, the third network interface was renamed from LAN2
to WAN2
, and instead of connecting it to an internal switch, the third network interface was connected to a new ISP.
- Let's use the Windows 2012 R2 machine to access the WebGUI console.
Note
Additionally, you can also use the Windows 7 client system to test the connectivity.
- Let's move on to the configuration process for load balancing and also for failover.
- Open the WebGUI of pfSense from Windows Server 2012 R2. If you remember, the pfSense server IP address is
192.168.1.1
. - Navigate to that IP address and...
