We can combine ACME and LetsEncrypt with HAPRoxy using pfSense. As part of our pfSense Support Services, Bobcares provides answers to all of your questions.

Integrating ACME and LetsEncrypt with HAPRoxy using pfSense

Using HAProxy, we can set up PfSense to function as a reverse proxy. This indicates that it is capable of accepting incoming HTTP and HTTPS requests and forwarding them to backend web servers. For load balancing and directing incoming web traffic, HAProxy is a potent tool.

Although Let’s Encrypt provides free SSL/TLS certificates, we must update them regularly, usually every 90 days. The Let’s Encrypt certificate application and renewal processes are automated using the ACME protocol. It allows PfSense to use Let’s Encrypt to automatically obtain, manage, and renew SSL/TLS certificates.

We can incorporate Let’s Encrypt and ACME with HAProxy using PfSense. We provide the domains for which we want SSL/TLS certificates when configuring ACME within PfSense. To request and get certificates for the defined domains, ACME interacts with Let’s Encrypt.

The incoming HTTPS traffic to the backend servers can be secured using these certificates by configuring HAProxy to use them once the certificates have been received. Decrypting incoming HTTPS traffic and sending it to the backend servers through HTTP or HTTPS, HAProxy serves as the SSL/TLS termination point.

Advantages

1. For websites or web applications, this configuration automates the process of getting and renewing SSL/TLS certificates, assuring their security.

2. To increase speed and make certificate management simpler, we can offload SSL/TLS encryption and decryption from the backend servers to the HAProxy load balancer.

3. HAProxy is a flexible option for controlling incoming web traffic because we can set it up to handle routing, load balancing, and other advanced capabilities.
