Create an Elastic IP 2. Create a Network Interface (for RDP) with the same Subnet ID and VPC ID of your instance 3. Associate the Elastic IP with your new Network Interface 4. Assign the new Network Interface to your instance 5. Reboot 6. Use the Elastic IP for RDP connections only (Make sure security groups are correct)
