SQL server issue

I am setting up one of my district’s with avast. We are hosting it on a VM and when I go through the set up process, we point our districts back to full SQL server we have on site. When I get to that page on the EA setup and select use full MS SQL Server, it can’t connect. First question is what ports do I need to have opened on our firewall for this to work? I set up the database prior to the EA setup so I have that the create avast database option unchecked. I can remote into the SQL server from this machine, so I know I can get to it, just wondering if it is a port issue or what?
