I'm trying to configure an Azure Internal Load Balancer, I have created in Basic SKU and Standard SKU. I want to use it with a SQL Server VM (TCP 1433), but is not working, when I test it with tcping to the front-end IP and port 1433 does'n respond. I have check the health probe, originally I created to test to 1433 TCP port, but latter change it to TCP 3389, also TCP 445, but it does'nt work eather.
I have tested the load balancer from a VM on the same subnet that the Load balancer is on, and also from my onpremise network (via VPN).
I have checked the NSG and everything looks good, I have created an incoming rule to allow "Azure Load Balancers" access to my Vnet, and also an Outgoing Rule to allow any traffic from my Vnet to "Azure Load Balancer", but it does'n work.
Also, I disabled Windows Firewall on the backend server.
Is there a way to check the result from the Health probe? Is there anything else I can check?
