Details:

The recent Azure update announces the general availability of custom port support for Azure Database for MySQL – Flexible Server, allowing users to specify a custom port number within the range 25001 to 26000 during server creation for both public and private access-enabled deployments. This enhancement addresses the need for greater flexibility in network configuration and security alignment, facilitating smoother integration with existing applications and organizational security policies.

Background and Purpose:
By default, Azure Database for MySQL – Flexible Server uses the standard MySQL port 3306 for client-server communication. While this default port is widely recognized and supported, some enterprise environments impose strict network security controls that require the use of non-standard ports to reduce exposure to automated attacks or to comply with internal network segmentation policies. Prior to this update, users could not customize the port at server creation, limiting their ability to align the database service with their security postures or application requirements. This update enables customers to specify a custom port within a defined range, enhancing security and compatibility.

Specific Features and Detailed Changes:

• Custom Port Range: Users can now select any port between 25001 and 26000 during the creation of a Flexible Server instance.
• Applicable to Both Access Types: This feature applies to servers configured for public access as well as those restricted to private network access, ensuring consistent flexibility regardless of deployment model.
• Default Behavior: If no custom port is specified, the server continues to use the default MySQL port 3306, maintaining backward compatibility.
• Configuration at Creation: The port must be specified at server creation time; changing the port post-deployment is not supported, ensuring stability and predictable network behavior.

Technical Mechanisms and Implementation Methods:
When a Flexible Server instance is provisioned with a custom port, Azure configures the underlying network security groups (NSGs) and firewall rules to allow inbound traffic on the specified port. The MySQL server process is configured to listen on the selected port, and connection strings must be updated accordingly by clients. For private access servers, the custom port is opened within the virtual network, while for public access servers, the port is exposed through the public IP with appropriate firewall rules. Azure’s management plane enforces these configurations automatically during provisioning, minimizing manual network configuration.

Use Cases and Application Scenarios:

• Security Compliance: Organizations with strict network security policies can avoid using the default port 3306, which is commonly targeted by automated scans and attacks.
• Application Compatibility: Legacy or third-party applications that require or expect a non-standard port can now connect without complex network workarounds.
• Network Segmentation: Enterprises implementing micro-segmentation or port-based access controls can better integrate Flexible Server instances into their security zones.
• Multi-Database Environments: Running multiple MySQL instances on the same network segment without port conflicts is simplified by assigning distinct custom ports.

Important Considerations and Limitations:

• The custom port must be within the specified range (25001–26000); ports outside this range are not supported.
• Port configuration is immutable post-deployment; changing the port requires creating a new server instance.
• Client applications and connection strings must be updated to specify the custom port explicitly.
• Network security rules and firewall configurations external to Azure (e.g., on-premises firewalls or VPNs) must be updated to allow traffic on the chosen port.
• Some managed services or tools that assume the default MySQL port may require configuration changes to support custom ports.

Integration with Related Azure Services:

• Azure Virtual Network (VNet): Custom port support integrates seamlessly with VNet service endpoints and private access configurations, enabling secure, private connectivity on the specified port.
• Azure Firewall and NSGs: These network security components automatically accommodate the custom port during server provisioning, but administrators must verify that any additional custom rules align with the chosen port.

• The update supports both IPv4 and IPv6 public IP addresses that customers bring into their Azure environment and register for use.

Technical Mechanisms and Implementation Methods

• Customers must first bring their public IP addresses into Azure using the Azure BYOIP process, which involves IP prefix registration, validation, and ownership proof via Azure Portal or CLI.
• Once the IP prefixes are registered and announced via Azure’s network infrastructure, these IP addresses become available for assignment.
• During Azure Firewall deployment or configuration within a secured Virtual WAN hub, administrators can specify these customer-owned public IP addresses instead of relying on Microsoft-assigned IPs.
• The Azure Firewall instance then uses these IPs for inbound and outbound traffic, maintaining consistent public IP presence.
• The secured Virtual WAN hub architecture ensures that the firewall is integrated with the global transit network, and the BYOIP IPs are advertised appropriately for routing.

Use Cases and Application Scenarios

• Enterprises with strict compliance or regulatory requirements that mandate use of owned IP address ranges for outbound traffic.
• Organizations aiming to maintain consistent public IP addresses for reputation management, such as avoiding IP-based blocking or blacklisting.
• Scenarios requiring IP address continuity during migration from on-premises firewalls or other cloud providers to Azure Firewall in Virtual WAN secured hubs.
• Multi-region deployments where centralized IP address management is critical for governance and auditing.

Important Considerations and Limitations

• Customer-provided IP addresses must be registered and validated through Azure’s BYOIP process before use. This process can take several days depending on verification steps.
• Only public IP prefixes that are owned and verifiably controlled by the customer can be used; Microsoft does not support IP spoofing or unverified IPs.
• The feature applies specifically to Azure Firewall instances deployed in secured Virtual WAN hubs and may not be applicable to standalone Azure Firewall deployments outside Virtual WAN.
• Proper routing and network configuration are required to ensure that the BYOIP addresses are correctly advertised and reachable.
