SQL Server database not publicly accessible through port 1433 - sql-server

Alright, I know this sounds pretty basic, but it is eluding me. I have a local server with SQL server 2017 installed (Express Edition, because - Free). I can access the database when remoted into the server without issue. The problem is when I try to access the server using the public IP rather than the local hostname. My router has this server in the DMZ currently and port forwarding is setup for port 1433. The server firewall is currently even turned off and I still cannot see it.
The SQL server does have TCP/IP enabled, it is listening on port 1433.
If you need any further information, let me know. I've been troubleshooting this for two hours and just lost at this point. I am no where near new to technology and servers, but not too familiar with SQL Server.

Make sure you have enabled remote connections.

What port does Microsoft SQL Server Management Studio use for database connections?

I am using Microsoft SQL Server Management Studio 17 to connect to a remote Microsoft SQL Server database. Looking at the connection dialog of Studio 17, I don't see any port number setting. Google tells me that Studio uses port 1433 by default.
I tried to use telnet to check if port 1433 is listening on the remote server: telnet example.company.com 1433
However, the connection failed. How can I find the port used for this database connection?
You could connect SSMS to your DB, run ProcessExplorer and examine the properties of ssms.exe. On the "TCP/IP" tab you possibly find what you are asking for:
Make sure you have connectivity to the server first. Since you mentioned "remote" there could be a firewall in the way, so your solution is going to depend on your network topology.
Can you ping the server? If ping works, I would reach out to the owner of the server and verify the DB connection parameters. Maybe your IP needs to be whitelisted. Etc. Etc.
Check if the server host has inbound port 1433 enabled, and whether TCP/IP is enabled using the SQL server configuration manager. If the SQL server instance in question sits on the cloud, you might want to check the specific provider's firewall rules on the container and adjust to permit 1433 inbound connections. The port setting entirely lies on where the actual SQL server instance sits. The management studio in your remote client will not be using any port.

Unable to connect to SQL Server on domain

I have been trying to connect to the SQL server in my domain for several days. I have a virtual box network with a client and a server. Only the client can’t find the sql server on my server. I followed all the steps to allow my database to comminuqer on port 1433 but nothing changes.
I don’t know what to do, I enabled TCP/IP with port 1433 and allowed connections in my database, as everyone recommends.
I have no server proposal and when I test with ip, I also have a mistake :
I added a new rule on my server:
The answer may be simple for some but I am not an expert in software development, I hope some will have answers.
Thanks in advance:)

Connecting to SQL Database Server Remotely

I'll preface my question with: I am an absolute beginner with respects to the nature of MS SQL Server and have a layman's understanding of networking and 'computers' in general...
So, I'm trying to replicate an environment where:
There is an 'application server' which hosts HPE's ALM
This communicates with a database server with a Microsoft SQL Server DB
I currently have Microsoft SQL 2012 Server with a sample DB uploaded onto it on one laptop (Laptop 1) and the ALM software on the other laptop (Laptop 2). Both are connected to the same WiFi network.
Laptop 2 is asking me for Database parameters such as:
DB Host Name
DB Port Number (1433 by default)
OR Connection String
I have little idea of what I'm doing - I'd have thought it might be possible to connect to the DB through some sort of variant of the IP address of Laptop 1... but I'm unsure.
How can I connect to a MS SQL 2012 DB from one laptop to another? I realise this is probably a loaded question - I'd be happy if someone can point me in the right direction rather than an exact answer!
Thanks guys,
ST
I see two potential issues:
A corporate laptop might have firewall restrictions. So, you have to
open port 1433 for SQL Server.
Possibly you are playing with SQL Express, which by default, does not
have TCP/IP connection enabled. To enable it run "SQL Server
configuration manager", go to Network
configuration->Protocols->TCP/IP->Enable->restart SQL Server. Also check other properties. If static port 1433 is not set - set it.
Two types of adjustments must be set before connecting to the remote SQL Server. These settings are necessary because without them the connection to the remote SQL Server will not be able to be successfully created
Configuration settings:
-The SQL Server instance to allow the protocol being requested
-Allow access through the Window Firewall
1- Enabling TCP/IP protocol
2- Configuring Windows Firewall

Create ODBC Connection from Access to SQL Server

I need help connecting from a blank access 2010 database to my remote SQL Server 2005 database. This is because I'm going to write all my client apps in Access, and store everything on the server with SQL Server. I'm using the wizard, and trying to make a new DSN. What do I put for:
Which SQL Server do you want to connect to?
Server:
The server is windows server 2008, and it is remote. I've been connecting to it with a .RDP file, but I'm not sure how to set up the link.
Please ask me to clarify anything that doesn't make sense.
Thanks.
Enter the IP address or the Windows Host Name for the server that has SQL Server on it.
You'll need to make sure that your server has port 1433 open in it's internal software firewall. If you're going through any kind of router that router will also need to have port forwarding and possibly the firewall opened up for port 1433.
Also, you'll need to make sure that your SQL Server instance is setup to listen on TCP/IP with port 1433 (unless you choose a different port).
You might be best off trying to connect to it from SQL Server Management Studio first. Once you have that working you should have an easier time setting up your DSN.

connect sql server 2005/2008 over internet

How do I connect to SQL Server 2005/2008 using Management Studio or other desktop application over the internet?
Check out WCF Data Services:
http://msdn.microsoft.com/en-us/data/bb931106.aspx
That way, you don't have to totally expose your database server out to the internet, but you get fine grained control over what gets exposed and who (which type of user) can see or modify what.

I finally solved this by:
Changing default SQL Port to 8080 from 1433 (our ISP was blocking)
Turning off Windows Firewall on the server. I know this is not a long term solution, but at least I was able to pinpoint the problem. I had set two inbound firewall rules to allow port 8080 and SSMS program, on the server. I created an outbound firewall rule on the client for SSMS (but don't think this mad a difference).
I had to change all apps to use the new port instead of the default port. I had to configure our router to handle the new port 8080 and forward to the database server.
I will modify the Windows Firewall settings to see what was blocking SSMS.
DB Server: Windows 7 Pro 64bit 24 GB RAM
If you put 'your' SQL server (any brand, I'm not bashing) on the internet ... it won't be yours for long, unless you add some rather effective security measures ...
I suggest you look into VPN.
To be able to access your database over the internet, you will need to make sure that the server that hosts the database is accessible over the internet and the port that the database instance uses is open on that machine. You will also need to allow remote connections using the SQL Server Configuration Tool.
For Management Studio access I would recommend rather than opening the server to the outside to use a VPN solution that allows you to create a secure connection to the server and from there you can use the server name or IP to connect as if your machine is part of that network.
For the desktop application I would recommend looking into having the data be consumed through a web service or WCF rather than needing to have a direct connection to the database over the internet.
Hope this helps.
Firstly, if we put security consideration on the side, you have to configure SQL server (sql surface area configuration) to accept traffic, then you have to open proper ports on you server and allow inbound traffic thru to your router to the SQL server.
When you open sql server management studio in connect to server window and at the server name type the IP of your server and enter your username and password.
correct format : IP\InstanceName
you should have a user on target database.
