Can we create a rule that prevents someone adding a DB Firewall Rule with the name ClientIPAddress*** ??
Thanks in advance,
Azure SQL database use the firewall rules to control the access. For example, create a firewall rule to allow the access from the client through IP address.
To be able to create and manage IP firewall rules for the Azure SQL Server, you will need to either be:
in the SQL Server Contributor role
in the SQL Security Manager role
the owner of the resource that contains the Azure SQL Server
We can't create a rule that prevents someone adding a DB Firewall Rule with the name ClientIPAddress***. But if someone is not in these roles, they don't have the permission to add role with client IP.

I have a server and a database on Azure and I connected it to SQL Server Management Studio 2017. I want to allow remote connection to my server but I can't get into the "server properties". I'm on free trial on Azure, and the firewall is on with "allow access to Azure services" with my IP on the whitelist.
On right click, the "properties" option doesn't appear
This option is for SQL Server instance not for Azure SQL Database instance.
Azure SQL Database instance is remote database in cloud, you don't need to set it since you have set the special firewall.
If you don't create the firewall rule, you can not connect to the Azure SQL DB.
The Azure document said that: A firewall rule is required to connect from other Azure resources and from on-premises resources.
Reference: Server-level IP firewall rules.
We can think that set firewall rule is equivalent to set SQL Server remote connection.
Hope this helps.
In Azure Server/Database firewall we can set the IP from which connections to the SQL Server can be made. However if I set any IP address eg. 101.202.203.204, then all users of the database can connect through that IP.
There is one user which is used by the application. I do not want anyone to connect to the production database using this username. This connection should only be permissible from the VM hosting the application in Azure.
In SQL Server there is a feature named Logon trigger wherein I can determine the username and the IP address from where the connection is being made and accordingly refuse if the connection request is invalid. This feature would have been helpful, however this feature is not available in the Azure SQL Server which I am using as a service.
Thanks in advance.
I'm not sure that this is the best way to secure a SQL Server/SQL Azure database, but technically you can do this using a login trigger where you check the user name and the IP address in the trigger. There's an example in the docs for triggers here that is basically what you are requesting (checks the login name). You'd just need to join with sys.dm_exec_connections and validate that the IP address is what you wanted.

A user is trying to connect to an Azure SQL Database via SQL Server Management Studio (SSMS v16.5.1).
The user's current IP address is not listed in the Azure SQL Server's firewall rules.
Because of this the user is shown the New Firewall Rule dialog.
When the user signs in using their Azure Active Directory (Azure AD) credentials they get an error message saying:
Account has no subscriptions
Clicking "Details" shows:
We experienced issues in connecting to Azure
Additional information:
login account does not have Azure subscriptions.
(Microsoft.SqlServer.Management.ApplicationAuthenticationManagement)
Why is the user getting this error message and how can they add a new firewall rule for their IP address?
Azure support have shared the below with me, based on an Azure documentation article.
Given an Azure SQL Server, only the Active Directory admin or SQL Server admin have permissions to add firewall rules at the server level.
The above error message (somewhat obscurely) indicates that the user is neither.
My personal experience also suggests that Azure AD accounts that are assigned as Subscription Co-administrators can also set firewall rules.
If, and only if, giving the user permissions is appropriate, this can be done by one of three ways:
Specifying the user as the SQL Server admin.
Setting the server's Active Directory admin to be an Azure Active Directory Group and making the user's AD account a member of this group.
Making the user a Co-administrator for the Subscription via https://manage.windowsazure.com/
Be sure to understand the security implications of each option before taking action.
Look at these two tutorials that will be live shortly (later on 1/13/2017):
https://learn.microsoft.com/en-us/azure/sql-database/sql-database-control-access-sql-authentication-get-started
https://learn.microsoft.com/en-us/azure/sql-database/sql-database-control-access-aad-authentication-get-started
These tutorials discuss using server and database level firewall rules with SQL Server authentication and Azure Active Directory authentication.
I hope these help,

In Azure Portal (https://portal.azure.com/#resource/subscriptions/{Your-GUID}/resourceGroups/AdminPortalDev/providers/Microsoft.Sql/servers/wjidentityserver/databases/{Your-DATABASE_SERVER}/overview )
Select your database
Select "Overview"
"Set server firewall" on the toolbar
Add client IP on the toolbar
Then you will be able to connect from the new IP address.
I was able to add the IP address without being administrator.
The steps in more details are described in https://learn.microsoft.com/en-us/azure/sql-database/sql-database-security-tutorial#create-a-server-level-firewall-rule-in-the-azure-portal.
Other question Client with IP addres is not allowed to access the server Azuredb describes more meaningful message and the same resolution.
I have created an Access 2013 web app which creates an Azure SQL database behind the scenes on our O365 SharePoint web site. I can access this database using SSMS studio (I have the professional version not the express version).
I would like to link to the Azure database tables or be able to copy the database. The reason for this is that I cannot create views in the Azure database and the Access web app is too limited for our external reporting needs. We don't need to create views or tables in the Azure database we only need to access the information stored in its tables.
Whenever I try to right click on the Azure database to perform a task I receive the following error.
Cannot open server 'xxxxxxx' requested by the login. Client with IP address 'xxx.xxx.xxx.xxx' is not allowed to access the server. To enable access, use the Windows Azure Management Portal or run sp_set_firewall_rule on the master database to create a firewall rule for this IP address or address range.

How do I take care of this error or how can I link to the Azure SQL database.
When viewing your database in the Azure management portal, there is an option on the right hand side that says Manage allowed IP addresses. That link will take you to a page where you can enter IP addresses that will be allowed through the firewall.
Here's a link to the MSDN article: How to: Configure Firewall Settings (Azure SQL Database)
Manage Server-Level Firewall Rules through Transact-SQL
Launch a query window through the Management Portal or through SQL
Server Management Studio.
Verify you are connected to the master database
Server-level firewall rules can be created, updated, or deleted from within the query window
To create or update server-level firewall rules, execute the sp_set_firewall rule stored procedure. The following example enables a range of IP addresses on the server Contoso.
EXEC sp_set_firewall_rule #name = N'ContosoFirewallRule', #start_ip_address = '192.168.1.1', #end_ip_address = '192.168.1.10'
I am new to SQL Server, and I have been tasked with setting permissions on a remote server. What I need to do is limit the domain admin from having access to any of the DB's on a particular server. How can I accomplish this?
Remove BUILTIN/Administrators from the SA group.
Important! Before you do this make absolutley sure you have either:
the password for the "sa" account
or
your domain account is a member of the sysadmin server role
Otherwise you might find yourself locked out of the server.. not that this has ever happened to me.. ;-)
