[yodaphone]

I am totally new to opnsense as i migrated from pfsense. The HAProxy 3.0 UI is new to me and I cant figure out how to do it. Can someone please write an updated guide for HAP 3.0 ?
this is my requirements

Real Server IP: 192.168.1.50:80 - webserver listening on port 80

I have configured a wildcard cert

Now how do i do this?

PS: For now i'm using Caddy to do the reverse proxy for me but i'd rather do this on opnsense so that i dont have to maintain another server
