I'm setting up Auth0 integration with an application that uses an existing database that stored usernames and password hashes. The database is stored in Azure SQL Database, and I need to configure the firewall rules to allow Auth0 to be able to connect to the database.
What is the IP address range that Auth0 uses to connect to custom databases?
Within the Auth0 configuration page for setting up the Database Action Scripts for connecting to and working with your custom database, there is a list of originating IP Addresses below the script editor. You can setup the Azure SQL Database Server IP Whitelist to allows the specific IP Addresses listed.
The display of the IP Addresses, look like the following, but you'll want to use the IP Addresses it lists on your account just in case they may differ from this screenshot.

I have a Website (App Service), 1 Sql Server with 2 databases on it.
Each month I randomly get an error:
Cannot open server 'myServer' requested by the login. Client with IP address 'xx.xxx.87.3' 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.
It may take up to five minutes for this change to take effect.
My question is, how do I know what application/service this IP address is?
It's not the IP address of my website and if I ping the CNAME of my database, it doesnt match this IP. But if I don't add it, my whole site doesn't work.
I must add this manually once per month, when something changes. How do I find out what this IP address is connected to?
Basically, there are 2 ways to solve your issue:
Specify Allow Azure services and resources to access this server as Yes on your SQL server firewall-config so that your SQL server will allow all Azure resources to access.
Adding all of the outbound IPs of your Azure app service into your SQL server firewall whitelist. It has a higher security level than the first way. You can find all the outbound IPs on Azure Portal here:
I understand that Microsoft Azure is very secure and the Azure SQL Server as well. However, the question is bit scenario based:
I'm accessing Azure SQL Server DB using SSMS, which is asking me to login using SQL Server authentication.
In Azure DB firewall security setting when I'm trying to add my current PC IP address ( which is Dynamic in nature ),its not adding.However, its actually considering my ISP provided IP address. The questions are: why its not allowing me to add my current IP address? Should not there be a security issue, if its considering my ISP IP ( which I can found "what is my IP") ? How and what level of security Microsoft is providing in this case? Is not it that, if someone will get my SQL Server credential they will go inside my SQL Sever in Azure?
OR
is it like that, the HOST/Computer name and IP address (which got via What is my IP) should be matched then the SQL Server credential will work? - Which is kind of more secure.
Hope I have explained this correctly.This is just to get more clarification not to compare.
I understand that, I think, I should have static IP. But, the local IP is dynamic.
Thanks.
It is the IP address assigned by your ISP what Azure SQL Database firewall can "see". That is the one you need to add as firewall rule. The private IP address your computer is using on your local network cannot be "seen" by Azure SQL database firewall.
Azure SQL Database security is more than just a firewall rule. All data in transit coming from any Azure SQL Database or going to any Azure SQL Database is encrypted. Azure SQL Database does not allow non-encrypted connections. All this is happening on TCP port 1433. You cannot communicate to Azure SQL Database on a different port.
When a client first attempts a connection to SQL Azure Database, it sends an initial connection request. Consider this a "pre-pre-connection" request. At this point the client does not know if SSL/Encryption is required and waits an answer from SQL Azure to determine if SSL is indeed required throughout the session (not just the login sequence, the entire connection session). A bit is set on the response indicating so. Then the client library disconnects and reconnects armed with this information.
When you set Encrypt to true you avoid the "pre-pre-connection", and you are preventing any proxy from turning off the encryption bit on the client side of the proxy, this way attacks like man-in-the-middle attack are avoided.
When secure connections are needed, it is recommended to enable "Encrypt connection" setting on SSMS.
In addition to all this, when you create a new database on Azure SQL Database data at rest is encrypted. Transparent Data Encryption is enabled by deafult.
I would like to connect to Azure SQL server from a Window server via SSMS. In the “set server firewall” from Azure, I have given my server IP ( from the system I would like to connect). I need to know the destination IP adders of the Azure DB Server. From Azure portal the location is showing central US . To allow firewall I need to know the destination IP address.
My questions are:
1. As Central US could have multiple IP addresses, do I need to provide all IPs to my Firewall team?
2. How can I know the destination IP address ( i.e. Azure) so that I can provide that to my firewall team?
Note: From SQL server management studio, the tcp default port for SQL is enabled and services are running fine.
Hope I have explained it correctly.Thanks
No. You cannot get a static IP address assignment for your Azure SQL Database. Moreover, what you refer (mysqlserverdatabase.mysql.database.azure.com designates your Azure SQL Database Server, not a single Database. This is a logical server, in which you can put up to 149 Databases (150 with the Master DB).
You have to workaround your requirement for static IP address assingment to work with the DNS Name (mysqlserverdatabase.mysql.database.azure.com).
Otherwise if your company firewall can't work with the DNS Name ,you need to set the server connection policy to Proxy as documented in Azure SQL Connectivity Architecture. This allows the database gateway to proxy all traffic between the client and the DB server. The gateways all have static IP addresses, which are listed in the above document.
If you have setup a VNet in Azure, checkout VNet Service Endpoints to connect Azure SQL.

From Bluemix I want to access an application in a customers data center using Secure Gateway service. I also want to give access to the destination (the customer application) to the Bluemix application only.
In the Secure Gateway dashboard under Advanced options of the gateway or the destination definition is a Network option where I can specify an IP address or address range plus port or port range. The help text says: "Set this destination to private to only allow access from specific IPs and ports." This is exactly what I am looking for.
But: How can I use this with a Bluemix app? I don't know the IP address of the Bluemix app. I am aware that I can figure it out but it is not static, the moment I stop and restart an app on Bluemix, the IP address may change. So this setting of the Network option would have to be done by some API call from the Bluemix application itself. Is this possible?
If not, why have this function at all?
The cloud application will use the "cap-sg-prd-<#>.integration.ibmcloud.com" hostname and the port they were given to connect into the cloud service. The client uses the destination configuration, which is downloaded to the client, to perform the backend, on-premises connection to their on-premises resource. So only their cloud application need to know about the cap-sg*/port number, all other connectivity is taken care by using the already established SecureGateway client connection.
In the form for the IP address you can also specify hostnames. You could try to provide the hostname of your Bluemix app. In my tests I did not succeed and had the entire connections cut off. Thus I cannot recommend trying to restrict connections right now.
By binding your Secure Gateway to the app or, even better, utilizing user-provided services to bind a database to an app you can leave the connection information internal to Bluemix. Here is a blog post with steps for user-provided services and on github is a demo for on-premise database integration utilizing the user-provided services and the Secure Gateway.
The hint regarding hostnames can be found in the Bluemix documentation for the Secure Gateway. The information about the Secure Gateway in the Knowledge Center is shy about it.
Apparently one must explicitly specify (whitelist) the IP addresses that will be allowed access to a SQL Azure DB. I want, though, to have N-gazillion* users that will access these tables for data specific to them.
delusions of grandeur/megalomania
Will these need to first provide me with their IP address so that I can add it as a valid entry, or is there a programmatic way to do it, or some other workaround?
It would be advisable to have some sort of middle ware access the db and not your clients directly.
However if you want any IP to be able to connect to the db just add this entry to the firewall list:
Azure Portal -> Databases -> Servers -> Configure and add the following rule:
How will your users be accessing the DB, via a Web App (front end) or directly (I assume you won't give users direct access to your DB?), if its via a Web App (presentation layer) then all you need todo is grant access to this IP address of the presentation layer/service layer (and if hosted in Azure its beside it).
SQL DB Azure has two types of access restrictions (more info here) "Windows Azure SQL Database Firewall"
Server-level firewall rules:
Database-level firewall rules
You could either open up all IP address 0.0.0.0 - 255.255.255.255 (not very secure) or come up with more finer grained policies based on the above Database firewall rules.
The only way is to do it is via SQL query. Azure shows only Firewall Server rules to be visible only on the portal but on database level the only way is via SQL.
-- Enable Allconnections.
EXECUTE sp_set_database_firewall_rule N'Allow All', '0.0.0.0', '255.255.255.255';
Login to azure Portal
select your database subscription
click on Tools
Now there is option 'Open in VisualStudio' (click on it)
You can see "Configure Firewall" click on it.
Add you new IP.
Done :)
If you let them talk directly to your database (for example via SSMS) you need to enter their IP (or you can just whitelist the whole range). Usually they will use your database via your own API, then it's not needed to whitelist their IP addresses.
