Associate static IP to a Azure SQL server/database - azure

I need to associate a public static IP address to points to an Azure SQL server, the server only has DNS name but doesn’t have IP address. I already tried Azure Load Balancer, Trafic Manager and DNS, and in any of the services there is an option to associate a static IP that point to the Data Base Name, for example the DB name is: testnetmarksrv.database.windows.net
Any options…?

This architecture provides the answer Azure SQL Database gateway IP addresses .
The table with the Public IP addresses for each region is what you will need to use for your firewall configuration with the Public IP address of the gateway as the destination address on your firewall and also allowing traffic outbound on port 1433 as this is the only port that the gateway will listen on.
I performed a couple of test to ensure that mydatabase.windows.net resolves to the IP address displayed in the table and it seem to have worked for me. I dont know if this is the official record Microsoft has for listing the public IP addresses for their IP addresses as I could not see some of the newer data centers on that list. The other thing that you will need to do is to set your Azure SQL Datase connection to Proxy mode. The following powershell will set that.
Get SQL Server ID
$sqlserverid=(Get-AzSqlServer -ServerName sql-server-name -ResourceGroupName sql-server-group).ResourceId
Set URI
$id="$sqlserverid/connectionPolicies/Default"
Get current connection policy
(Get-AzResource -ResourceId $id).Properties.connectionType
Update connection policy
Set-AzResource -ResourceId $id -Properties #{"connectionType" = "Proxy"} -f
I am not sure about why you have a requirement to limit outbound SQL traffic but will urge you to also have a look at restricting inbound connections to your Azure SQL Databases.
This should be done on the Azure SQL Server that your Azure SQL Database lives on. Below are some resources to help to configure a Azure SQL Server firewall rule/s and provides a number of methods to set firewall rules including through the protal, through SQL and through the commandline.

Hope this helps!

No. You cannot get a static IP address assignment for your Azure SQL Database. Moreover, what you refer (testnetmarksrv.database.windows.net) 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 (testnetmarksrv.database.windows.net).

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.
Currently most regions default to the Proxy connection policy if the connection comes from outside Azure, but this is changing on 2nd Jan 2019, so make sure to explicitly set the policy if you require static IP addresses.

SSMS IP address changes after disconnecting from Azure SQL server

We are connecting to Azure SQL server for our work through SSMS. We are whitelisting all the developers IP in Networking section of Azure SQL Server. Whenever we close SSMS connection all the time SSMS IP get changes. Then we need to go and update the new IP in Azure portal. Why SSMS changes the IP all the time. Any solution for this in SSMS settings.
Your ISP is properly providing you a dynamic IP. You can check your egress IP with a lot of online IP discover services. If it changes overnight/day e.g. https://wtfismyip.com/
To avoid dealing with IP Whitelists you could use a VPN Gateway or Express Route to tunnle your Devs to an Azure VNET and connect the Azure SQL DB with private Link into that VNET.
Alternatively, you could use a Bastion host to run SSMS there.
But in the End, there is nothing which you or Microsoft can do on Azure Side to prevent your client IP from changing when your ISP doesn't provide you a static IP.
Of course, you can ask them to upgrade your internet to a static IP address, or do you use multiple egress IPs in your company? In this case maybe speak with your network admin to get all egress IPs and whitelist those.

Access Azure Private Endpoint Using Azure VPN

I am trying to access resources that are secured behind private endpoint from a remote location using an Azure VPN Point-to-Site connection.
So far I have setup a conditional forwarder to send DNS requests to Azure's internal DNS IP address (168.63.129.16). With my setup I can resolve all my private endpoints using nslookup to their private IP addresses. I can also connect to services such as SQL server from my local machine (using SQL Server Management Studio in the case of SQL server).
The problem I am facing is that I can only access resources if I use a desktop client for a given service. If I try to do anything using the Azure Portal, I get an error stating that I cannot access resources using my Public IP address without adding it as an inbound IP address. Whilst this is certainly an option, I don't want to go down this road.
I am hoping there is an option where I can connect to private endpoint resources from Azure Portal whilst connected to my point-to-site VPN. Any ideas?

AfAIK, the process which you are doing is correct, To fix this issue try to update the local host file on client desktop to deploy a recourse with private endpoint please refer this link for more in detail
By default when you create a Private Endpoint in the Azure Portal it will automatically lock out public access. Service Endpoints operate by adding routes to allow traffic out of the virtual network to reach the public endpoint of the service selected. If you are access resources error, update firewall rules to communicate with your Azure resources you really need to configure v-net traffic on the firewall settings
Next option is conditional forwarder, in your scenario the ble from every v-net, its public ip it won't overlap with any private ips, it available from inside of azure v-net unique to each
In conditional for forwarder, client asks the ip of a host like www.seraltos.com .The dns server looks to see the answer if knows, if not a lookup will done based on root servers or forwarder to find the ip address returns that to the client

How to connect to an Azure SQL Server using the PrivateLink IP

I have an Azure logical SQL server to which I added a Private Link, the NIC is attached to an existing vnet\subnet. Our company's VPN is linked to that vnet and I can see other devices on the private link's subnet but not the SQL Server.
The SQL Server is reachable on the public URL (temporarily for testing) but trying to ping or tracert the server with the private IP fails, I can ping and tracert to other VMs on the same subnet.
I'm not using a custom DNS zone because it's imperative that we configure it with the IP and I haven't made any changes to our company DNS (I'm expecting not to have to).
Other than creating the private link and attaching it to the SQL Server, what else needs to be done? What am I missing?
I'am working on the same Issue. It's still not solved yet but there are some steps you need to do.
For the Connectivity it's required to add a DNS, especially if you want to connect from the On-Prem. Azure has a default DNS-Solution for Azure-Resources. The Problem is: From On-Prem you can't access the default Azure-DNS-Service.
So you have to configure a DNS-Zone (in Azure or On-Prem).

How can i connect to azure sql from my local machine without adding it to firewall? Note - Public acess is turned off

I want a solution wherein I can connect my local machine and other's as well without adding IP address manually in the firewall as it is a time-consuming process.
Each time I have to update the IP address in the firewall.
I tried connecting Azure SQL Server to Virtual network by the service endpoint SSMS. Then access virtual network by VPN gateway but it's not working.
You could set your local machines' IP range to the the SQL database firewall to allow these machines to access the Azure SQL database:
If you specify an IP address range in the database-level IP firewall
rule that's outside the range in the server-level IP firewall rule,
only those clients that have IP addresses in the database-level range
can access the database.
Ref: Azure SQL Database and Azure Synapse IP firewall rules
For example:
If you want access the SQL database through Vnet, you could create and add virtual network rule to the SQL database firewall:
For more details, please ref: Use virtual network service endpoints and rules for servers in Azure SQL Database
Hope this helps.

How to connect to Azure pass DB from a secure network

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.
