How-To: HAProxy/OPNSense - TCP Forward/Redirect

So, I have used HAProxy for a long time, but it was always by modifying the haproxy.cfg file. with OPNSense you have a UI in front of it and I am unable to find where the cfg file is stored to manually make the changes. That said, Can someone please describe how-to redirect a URI rdp.mydns.com to an internal ip address say: 192.168.1.13 (Port being redirected is 3389/RDP).

I tried to setup a condition and then use HTTP Redirect, but that is not working…

If you want to know where the config file is, log into the box and take a look at the ps auxww output.

I don’t understand what this is supposed to mean. Can elaborate how your configuration looks like and what you would like to achieve?
