VPC Configuration

Open the Security Groups console in AWS.
Search for Security Groups under Network & Security.
Locate the default Security Group that was automatically assigned during the Redshift configuration.
Edit the inbound rules of this security group.
Add a new inbound rule to allow traffic from your region’s IP range.
- Example for Stockholm region:
```
13.53.63.224/27
```
Set the Type to Redshift, and the Port Range should default to 5439 (the default Redshift port).
- This step is required to allow Kinesis Firehose to reach your Redshift cluster. If omitted, data will not be delivered.
