How to setup direct RDS connection through VPN

Setup Direct RDS Connection Connect to your VPN using your OpenVPN client and verify the connection is established with a private IP address Change your DNS settings to use Google's public DNS server (8.8.8.8): - On Windows: Go to Network Settings > Change adapter options > Right-click your network connection > Properties > Internet Protocol Version 4 (TCP/IPv4) > Properties > Use the following DNS server addresses > Set to 8.8.8.8 Test the connection using the MySQL command line: mysql -h your-rds-endpoint.amazonaws.com -P 3306 -u your-username -p If using a database GUI tool like DBeaver, create a completely new connection rather than modifying an existing one to avoid cached DNS settings Verify you can telnet to the RDS endpoint on port 3306 to confirm network connectivity: telnet your-rds-endpoint.amazonaws.com 3306 Usage Once the direct RDS connection is established, you can use any MySQL-compatible database client to connect to your RDS instance. The key troubleshooting steps if you encounter "unknown host" errors are: Ensure your VPN connection is active and stable Change DNS settings to 8.8.8.8 to resolve hostname issues Create new database connections in your client tools rather than reusing existing ones that may have cached incorrect DNS information Verify your security groups allow connections from your VPN IP range
