Hello.
I have an HAProxy instance running on a pfsense machine, and three IIS 8 servers.two of this IIS servers are running on the same network of the internal LAN address of the HAProxy. The third IIS server is running on other datacenter.
I have 3 backends configured to all of this servers, with one active server in each and the other servers as backup.
The diference betwin the three servers configuration is that in the two servers of the same network I have the LAN address configuured, and for the third external server I have the public IP (443 port NATed of course).
The 2 servers that are on the same network works fine with HTTPS protocol, but for the server that is on the external datacenter don't works. I recieve the erros:
"503 Service Unavailable
No server is available to handle this request."If I try to connect to the third server directly bypassing the HAProxy works.
I was capturing the traffic with wireshark, and I see that the connection to the twor servers that work on the LAN establishes as TLS protocol, but the connection to the external server establishes as SSL protocol. I guess that is the reason why don't works.
I will apreciate your help.
