Migrating from TMG 2010 to HA-PROXY as a reverse Proxy issues
-
Hello everybody,
I would need some help achieving my goal.
I'm currently trying to migrate from a Microsoft TMG2010 Setup to using PFSense with HA-PROXY as reverse proxy.
So far, I managed to make it work when accessing an Apache server on the backend, but I get "HTTP 503" when trying to access some SharePoint backends.I followed this tutorial: https://blog.briantruscott.com/how-to-serve-multiple-domains-from-a-single-public-ip-using-haproxy-on-pfsense/
So, here are some details:
OLD Setup:
Internet –> PFSense with NAT --> TMG2010 --> SharePoint ServerNEW Setup:
Internet --> PFSENSE with HAPROXY --> SharePoint Server.Here is the HAPROXY configuration

OK, I've also done a Fiddler trace and I got:
GET http://mydomain.com/favicon.ico HTTP/1.1

No server is available to handle this request.
So it seems it doesn't even reach the backend server.
Is there any special configuration to use if the backend server should also be accessed internally via a host-header ?Thanks.

Look like HAProxy doesn't see backend endpoint as alive.
What it says on HAProxy -> Status page? -
In the status page for the SharePoint backend I get: Unauthorized.
The site on SharePoint does allow anonymous access.Thanks
