I cannot get my Azure VM with SQL Server to connect from anything other than the local machine. This is a Windows VM where I downloaded and installed SQL Server manually. I am at a loss.
If I RDP to the machine and connect to SQL Server it succeeds. If I attempt to hit it from any other box on my Virtual Network it will not connect. I can ping the box and the name resolves to the proper IP address. Test-NetConnection shows that I cannot connect on port 1433, but I can connect on other ports like 3389.
Here is all I've tried/confirmed thus far.
TCP/IP is enabled in configuration manager and set to listen on port 1433. Remote access is enabled in configurations.
I added a port 1433 Windows firewall rule for all 3 profiles.
I turned off the Windows firewall for all 3 profiles.
Confirmed both machines are definitely on the same virtual network.
The default NSG rule is in place for any port/protocol on the same Virtual Network.
I added an explicit NSG rule for the source IP of another machine to any port/protocol.
I modified the rule that allowed me to RDP to the box from my personal IP to include 1433 in addition to 3389. Test-NetConnection succeeds on 3389 and fails on 1433.
None of these made a difference.
I created a new VM where the machine came pre-installed with SQL Server. It connects just fine from any other machine on the VirtualNetwork without making any changes to any firewall or NSG rules.
What am I missing?
Is SQL listening on the internal address and an allowed connection IP? http://www.mohamedmostafa.co.uk/blog/2009/10/10/setup-configure-microsoft-sql-server-to-allow-remote-connection-remote-sql-management-studio-access/
Sound like your MSSQL is setup with a dynamic port in the tcp/ip protocol. Check the TCP/IP protocol and if the port is blank, set it to the desired port (1433) and set NSG to allow communication on this port.

I have created the virtual machine on Azure and installed a free version of the SQL Server database. I have created a new login in the SQL Server to access the database. I also added the inbound rule to enable TCP port on the Azure portal of the virtual machine.
Now I am trying to access the SQL Server instance from my local computer over IP but it's not connecting. Is there anything I am missing? I am getting this error:
Use Configuration Manager to enable TCP/IP connections and listen on port 1433.
Add a Windows Firewall rule allowing inbound traffic on port 1433.
Configure the VM's Network Security Group to allow inbound traffic on port 1433.
I am trying to set up MS SQL Server Express 2019 to listen on TCP/IP and connect to it through IP address instead of shared memory. I am currently connecting through Windows Authentication and the SQL Server Management Studio (SMSS).
In the Configuration Manager, I have enabled TCP/IP and the desired IP address (192.168.0.198, port 1433). I have checked that "Listen All" is enabled, as is "Allow remote connections to this server" in SMSS. I also restarted the service after enabling TCP/IP.

However, when I try to connect, it gives an error.

Is it required to set up an account, does Windows Authentication not work with IP address? I also could not ping or otherwise locate the server listening. In the Windows Resource Monitor, there is no service listening on 1433. What could be the reason for this?
Thank you.
if "Listen on all ips" is set to true/yes then it uses the port in the last entry on TCP/IP networking settings. IF you have 5 ips (localhost, public ip, etc) then you have to scroll down (might not be in view). There is a settings for "all ips" with a port number like 53477. You can either pick "NO" to listen to all ips option, change the port, or use the 53whatever port # listed to connect. check firewall settings too.
On TCP/IP remove the 0(zero) in TCP Dynamic Ports.
I have a Windows Server 2016. In this server I have a SQL Server 2016 installed.
I must configure the sql server to allow remote connections because there are some databeses which synchronise with our local databases.
I do this by openning the SQL Server Configuration Manager, selecting SQL Server Network Configuration and enabling the TCP/IP protocol.
But, this causes a security gap.
I realised that the SQL Log File C:\Program Files\Microsoft SQL Server\MSSQL13.MSSQLSERVER\MSSQL\Log is constantly increaising the size.
By analysing the log file, I realised that there are some IP addresses tries to connect constantly with a wrong password (15 times per minute).
As I need to keep open the TCP/IP protocol, I tried to add an inbound firewall rule to the firewall but it doesn't change anything.
First, I tried to disable the TCP/IP and authorise connections from a defined IP. It didn't work.
Then, I tried to enable TCP/IP and block the port 1433 for any IP but it doesn't block. I can connect from a local pc.
Briefly, if I enable the TCP/IP, the remote connection is enabled to any IP. If I disable the TCP/IP, the remote connection is disabled to any IP. It doesn't consider the firewall rule.
Is there a way to enable the remote connection for a specific IP Address ?
Here is what I do to block the 1433 port (But I am allways able to connect via SSMS from a local computer ( which is in another domain ) :
I faced recently the same issue and fixed it by setting customised rule in windows Firewall:
1) Enable TCPIP, otherwise no connection will be possible
2) then you should use the windows firewall as follows:
first Block the port 1433 for any inbound connection
then add a customised rule to port 1433 for which you authorise connections from only specific Ip address, you can follow the steps explained in this link
Here is a screenshot of the firewall setting I have
Here is a screenshot of the port blocking setting I have
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

Networking VM Rules
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.
I am working on a system whereby I can update a small database from several locations. I wish to host the database on my home computer and allow connections to be made to the database from two other locations through tcp/ip.
I have done the following thus far:
Enabled TCP/IP for SQLEXPRESS
Allowed port 1433 tcp on my firewall
Allowed port 1434 udp on my firewall
Enabled SQLEXPRESS server to allow remote connections
I was hoping to be able to connect to the database by opening sql management studio on the other pcs and using the following format [ExternalIP]\SQLEXPRESS but as of yet I have been unable to do so. I have looked at what my external IP might be and i am getting two different values:
86.XX.X.XXX
66.XXX.XX.XX
Should I be using either of these values with this format to connect from the other sql management studios when everything has been correctly configured? Are there any steps that I am missing?
Named instances of SQL Server don't listen by default on port 1433, but instead on a random port determined at each service startup. It's the function of the sql browser service to provide clients with actual ports of each running instance (and that's done using the fixed 1434 udp port).
The necesary steps would be to configure the server to use a fixed port, then setup the firewall and router to allow that port. When connecting, just use the external IP address with the port but not the instance name (as that would invoke the browser service, which is unneeded with fixed ports).
To resume, necesary steps would be these:
Enable remote connections on the server.
Setup users and permissions as needed (Windows authentication is a pain over internet, so SQL authentication is strongly recommended)
Enable TCP/IP for the instance.
Configure the server to use a fixed port for connections (1433 being the standard). Look here for instructions.
Restart the database server.
Give permissions on the firewall to allow the server executable incoming connections on your selected port. At this point other computers in the LAN should connect.
On your router forward the port you opened to your local machine private IP (note that in Windows you must configure your computer to use a fixed local IP instead of DHCP).
Test with a client over internet or just using your external IP.
Note that for the connection from the remote client, as server name you must use 86.XX.X.113,1433 (the port number is separated with a comma, optional if it's 1433). Notice that there is NO instance name, even if you installed it as SQLEXPRESS or whatever. This is due having a fixed listening port (like the default instance by default). That eliminates the need of the browser service and udp 1434, and the pain of a dynamic port forwarding.
You should also check that your ISP most likely will give you a dynamic external IP, so clients might be reconfigured when that changes. Or you can use some dynamic DNS service.
