NGINX Redirect

[Junktroep]

I have a reverse nginx proxy running on an ubuntu box.
Running non standard ssl ports, an example of my config:

server {
    listen 9090 default_server ssl http2;
    server_name blabla;

    add_header Strict-Transport-Security "max-age=31536000; includeSubDomains" always;
    add_header X-XSS-Protection "1; mode=block";

    ssl_certificate /etc/letsencrypt/live/blablafullchain.pem;
    ssl_certificate_key /etc/letsencrypt/live/blabla/privkey.pem;
    ssl_trusted_certificate /etc/letsencrypt/live/blabla/chain.pem;
    include snippets/ssl.conf;
    error_page  497 https://$host:9090$request_uri;

    access_log /var/log/nginx/blabla.access.log apm;
    error_log /var/log/nginx/blabla.error.log warn;

    location / {
        proxy_pass        http://127.0.0.1:8080;
        proxy_set_header  X-Real-IP  $remote_addr;
        proxy_set_header        X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header        X-Forwarded-Proto $scheme;
        proxy_redirect off;
    }
}

I wanted to move this functionality to OPNsense, and it works nicely with the nginx plugin.

One thing I don't get to work the HTTP to HTTPS redirect.
In the example above I get this going with the: error_page  497 https://$host:9090$request_uri;
this redirects HTTP requests to HTTPS.

But I can't find this in the error pages overview in OPNsense, and no idea how I or even if this can be done.

Any tip or help is apreciated. Thanks.

"HTTPS Only" checkbox in Server config or "Force HTTPS" checkbox in Location config do the same with the

Code: [Select]

    if ($scheme != "https") {
        return 302 https://$host$request_uri;
    }

This checkbox does nothing for my config. Even after reboot.
On the opnsense reverse proxy server settings I have only specified a https port, just like in my example config.
It doesn't seem to like binding same port to https and http.

I still get: The plain HTTP request was sent to HTTPS port, error 400,
when connecting on http://mydomain.com:myport

yep, need to bind http also for this.
497 error_page is not in gui yet
so you need to use server hook for this imho (https://forum.opnsense.org/index.php?topic=31234.0)
there it will be possible to add a directive missing in the gui

[Junktroep]

The hook pointed me in the right direction
Creating the <uid>_post directory with a 497_error_page.conf in it.
Containing error_page  497 https://$host:9090$request_uri;
Makes http request to the https port redirect succesful.

Ps. adding the error_page 497 to the nginx.conf also makes it work.
But I guess this will not survive any modifications done in the GUI.
I hope this custom survives firmware upgrades.

Since this is a pretty nice way to redirect http to https I hope this will soon be added as defailt in GUI.
