初始 Azure VM 设置不允许任何端口连接（NSG 端口允许 VM 防火墙关闭）

Question

I've created a new Azure VM and tried opening 1433 for a remote database connection (I understand long term this shouldn't be a public port).

I've created a rule in my NSG to open port 1433, and entirely disabled windows firewall, and I still cannot get through port 1433.

If I go in and disassociate the NSG, then I can connect just fine, so it's not the server that's blocking, it's happening at the NSG level

This is a fresh install of Windows 2012 R2 Datacenter.

Here's my NSG

Answer 1

Check if SQL-Server service accept remote connections and if it's listening on 1433 port. Specify a source IP address for the rule (is absolutely not recommended to open a port to all). Do a port scan to the specific ip.
