-This sandbox setup is designed to help developers begin building the application. Once the application is ready for production, you can gradually request to increase the sending volume. If you need to send more messages than the rate limits allow, submit a support request to raise your desired email sending limit. The reviewing team will consider your overall sender reputation, which includes factors such as your email delivery failure rates, your domain reputation, and reports of spam and abuse, when determining approval status.

-- For basic access from a commmand-line tool, you can run `mysql` from the app's SSH terminal.
-- To connect from a desktop tool like MySQL Workbench, your machine must be within the virtual network. For example, it could be an Azure VM that's connected to one of the subnets, or a machine in an on-premises network that has a [site-to-site VPN](../../vpn-gateway/vpn-gateway-about-vpngateways.md) connection with the Azure virtual network.

+### How do I connect to a MySQL database that's secured behind a virtual network?
+
+To connect to a MySQL database, you can use several methods based on the tools and environments at your disposal:
+
+- **Command-line tool access**: 
+   - Use the `mysql` command from the app's SSH terminal for basic access.
+- **Desktop tools (for example, MySQL Workbench)**:
+   - **Using SSH tunneling with Azure CLI**:
+     - Create an [SSH session](../../app-service/configure-linux-open-ssh-session.md#open-ssh-session-from-remote-shell) to the web app by using the Azure CLI.
+     - Use the SSH session to tunnel the traffic to MySQL.
+   - **Using site-to-site VPN or Azure VM**:
+     - Your machine must be part of the virtual network.
+     - Consider using:
+       - An Azure VM linked to one of the subnets.
+       - A machine in an on-premises network that has a [site-to-site VPN connection](../../vpn-gateway/vpn-gateway-about-vpngateways.md) to the Azure virtual network.
+- **Azure Cloud Shell integration**:
+   - [Integrate Azure Cloud Shell](../../cloud-shell/private-vnet.md) with the virtual network for direct access.
