How to configure pfSense as multi wan (DUAL WAN) load balance failover router

Best/Tutorial

To configure pfSense as a dual WAN load balancing and failover router, you need to have two WAN connections and a pfSense firewall installed. Here are the steps to configure pfSense as a dual WAN load balancing and failover router:

  1. Login to the pfSense web interface and go to "System" -> "Routing."
  2. In the "Gateway Groups" section, click on the "+" button to add a new gateway group.
  3. Give the gateway group a name, such as "WAN Load Balance."
  4. In the "Gateways" section, click on the "+" button to add the first WAN connection. Enter the IP address, default gateway, and other details for the first WAN connection.
  5. Repeat step 4 to add the second WAN connection.
  6. Set the "Monitor IP" to a host that is reachable through both WAN connections. This is used to monitor the availability of each WAN connection.
  7. Set the "Load Balance" option to "Load Balance." This will balance traffic between the two WAN connections.
  8. Set the "Failover" option to "Failover." This will allow pfSense to automatically switch to the other WAN connection if one of the WAN connections fails.
  9. Save the gateway group configuration.
  10. Go to "Firewall" -> "Rules" and create rules for incoming and outgoing traffic to use the new gateway group.
rnThat's it! You have now configured pfSense as a dual WAN load balancing and failover router. The traffic will be balanced between the two WAN connections, and if one of the WAN connections fails, pfSense will automatically switch to the other WAN connection.
