Set Up pfSense HAPoxy Backend SSL

In relation to HAProxy, a backend can be described as a group of servers that receive traffic from the load balancer. These servers are configured to serve the same application or content.

In other words, HAProxy can be configured to load balance traffic across multiple backend servers using different algorithms.

On the other hand, SSL, short for Secure Sockets Layer is a protocol that provides secure communication over the internet. It is used to encrypt data sent between a web browser and a web server.

In short, SSL creates a secure channel between the client and server, and encrypting all data sent over that channel. We can use SSL certificates to verify the identity of the server and provide assurance to the client that they are communicating with the intended server.

The pfSense HAProxy backend SSL configuration involves setting up a HAProxy on a pfSense firewall or router to load balance traffic across multiple backend servers via SSL encryption.

Let’s take a look at how we can set it up:

1. First, locate the haproxy package under System / Package Manager / Available Packages and clicj the install button.
2. After that, we have to head to Settings under HAProxy in the Services section and configure the settings as per out requirements. Remember to check the Enable box before clicking Save.
3. Now, we have to create a backend. This is also referred to as upstreams in Nginx.
4. At this point, we have to create a frontend to route all user requests to right backend according to the hostname information.
5. Next, we have to create two firewall rules that involves opening TCP-ports 80 and 443 via WAN interface in order to open our HAProxy to the external world.
6. Finally, it is time to test the configuration is up and running.
