local services with its domain name and cert, (pfsense haproxy)

Hi all,

I'm a bit confused with the following situation and how to configure the dns/reverse proxy. Let's say I have configured a wiki on a local server (10.10.10.10) , it host other services so it's published on port 1234.

In local I access it as 10.10.10.10:1234

remotely I have configured haproxy on a pfsense router to proxy https://wiki.my.domain to 10.10.10.10:1234, it even has a nice letsencrypt certificate and everything.

How can I do the same in local? I know I can override the dns but it won't proxy to the right port.

Thanks
