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:

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.
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.

I am hosting an web app at azure.
My problem is, that my MySQL Database, that is not hosted at Microsoft Azure, requires an IP to be whitelisted. Otherwise I am not able to connect from the server to the DB.
Do you know which IPs should be whitelisted?
I have come across the IPs that are under Properties -> Outbound IP Adresses, fe.
Are the IPs that are inside that Block the adresses that try to access my database, should they be whitelisted? Can they change?
So, I have found out that these IP Adresses are the outbound adresses- YES, they can change. You can find out the IPs under https://www.microsoft.com/en-us/download/details.aspx?id=41653
Microsoft gives an IP range to every server farm (depending on your server location, eg. Europe, America...) - Your server IP can change within that IP range- when you want to whitelist your Server, you have to whitelist that range.
We are trying to register the Azure VM to our own DNS Server but not able to do so.
We have already setup the VPC, Virtual Network and Gateway to connect to our DNS server.
we have also specified our DNS server within the Virtual network.
From what I understand, you're looking to register your VMs internal IPs in your DNS server. Is that correct?
If so, Windows clients do this automatically when domain joined and will send an unsecured Dynamic DNS update when not domain joined but you need to create a DNS zone for the records and allow unsecured updates, which is not the default. Linux clients need a script added to the DHCP client to send the dynamic DNS updates. I'm in the process of creating a page on Azure.com for this and can share the commands in the meantime if you're using that setup.

I have a WebJob on an Azure Website that needs to connect to a VM Endpoint to make REST calls.
My Endpoint is configured to deny all except my company's IP range. Now what rule would I need to add or url should I use so my webjob can connect to the endpoint?
I have tried the following without success:
Allow my website virtual IP address in the ACL
Connect to the endpoint using the internal IP instead of the DNS without changing
the ACL
Connect to the endpoint using the public virtual IP instead
of the DNS without changing the ACL
This works but is not what I am looking for:
Remove the current ACL and allow all
Keep the ACL but add a /16 rule with my website IP
Thank you for your help, and let me know if you need precision!
I need the same thing but it seems as though is not possible right now. Looking at this answer on a related question:
Azure Web Sites do not have dedicated outbound IP addresses for each
deployment. This precludes you from using ACLs or Virtual Networks to
connect to your Redis / Solr virtual machines.
So even though you can have a (reasonably) fixed incoming IP address on Azure Websites, the outgoing address is highly unpredictable and as far as I can see, the only exclusion that you could make was to restrict it to the entire range of IP addresses for that data centre which is far from ideal.
A solution moving forward will be to connect your Azure Website and the VM on the same Virtual Network. As of my writing this it is still in Preview so it still is not ready for production use just yet.
