We are looking to Load Balance 3 x IIS Web Servers over HTTPS using HAProxy and need session persistence (Sticky Sessions), most users will come from a single external IP as they are office based.
From my reading so far it seems that this is possible but there are not many pfsense based guides out there.
The solution I have come to in my head is as follows
SSL Offload at the pfSense/HAProxy
Route to HTTP traffic internally
Use a cookie based session persistence
Does this sound anywhere near what we need to do in order to achieve our desired outcome?
Does anyone have a similar setups that they could screenshot so I can understand the setup better?
