The “http-request redirect” with HAProxy on pfSense

HAProxy, when used with pfSense, offers a simple way to set up HTTP request redirects. Here’s a simple steps to set it up:

1. In pfSense, go to System > Packages > HAProxy > Config files.

2. Find the frontend config file we want to modify.

3. In the frontend config section, look for the acl (access control list) directive.

4. Use the http_req keyword to set conditions for the redirect.

5. Then, employ the http-request redirect directive to specify the redirection details.

6. Save the config file.

7. Go to System > Packages > HAProxy > Service in pfSense, and click “Reload” to apply the changes.

For e.g., here’s how to redirect all HTTP traffic to HTTPS:

Here,

frontend webserver: Defines the frontend listening on port 80 (HTTP).

acl redirect_to_https hdr_ssl off: Checks if SSL is not present in the request header.

http-request redirect code 301 location https://%{host}%{uri}: Redirects matching requests with a permanent (301) status code to the corresponding HTTPS URL.

We must make sure the web server listens on the target HTTPS port (usually 443) and has valid SSL certificates.And test the redirection rules thoroughly to avoid unintended consequences. We can also consider using a separate frontend for HTTPS traffic if we have specific config for secure connections.
