HAProxy Reverse Proxy with subdomains

[mvdheuvel]

Hi,

I am struggling a while with HAProxy plugin.
I have a single IP address and a single domain name.
I have a VMware server with multiple webservers.
I want to configure reverse proxy, so that I can use my single domain name with multiple domain.

Example.

support.example.com --> server1
www.example.com --> server2
transfer.example.com --> server3
nextcloud.example.com --> server4

(internet address) --> opnSense --> webserverX (VMware)

I am not able to find the right answers in all the fora.
Can someone help me with this question if it is possible with opnSense, I starting to think opnSense is not the right solution for this environment.

I have followed that guide, but no luck with it.
It will always resolve to the latest made frontend.

Then probably something went wrong in Step 4 - it connects your hostname to a backend server.

Thanks,

The trick is that you use only 1 frontend server and add the rules for the different domains to this frontend.
