When configuring a security group for Vantage, set up the port ranges listed below for each Vantage instance so Vantage can be locked down to the local host. Port 1025 is blocked in the local instance until the DBC password is changed. If you are deploying a Teradata ecosystem, do not delete or modify the self-reference rule that is created for internal security group communication.
By default, NTP uses the Amazon Time Sync Service on a local IP. If you must use different NTP servers, make sure the VPC ACL setting is not blocking UDP port 123 for outbound traffic.
When deploying a Vantage MPP instance using AWS CloudFormation, access is restricted to IP addresses in the CIDR block specified in the Remote Access From parameter. If you have other Teradata software instances residing outside that IP range, you can edit the security group after deploying to add the necessary IP addresses. Teradata software instances that may need access to the Vantage MPP instance include:
- Teradata Data Mover
- Teradata Data Stream Controller
- Teradata Ecosystem Manager
- Teradata Query Service
- Teradata Server Management
- Teradata Viewpoint
If you are not deploying a Vantage MPP instance using a Teradata ecosystem solution template or deploying Vantage separately, you must add inbound TCP 22 and UDP 1001-1002 ports.
| Direction | Protocol | Port Range | Description |
|---|---|---|---|
| Inbound | TCP | 22 | SSH |
| TCP | 1025 | Vantage Service to AWS | |
| 3015 | Access to the CNS subsystem | ||
| TCP | 64432 | If using mainframe connectivity | |
| UDP | 1001-1002 | If using non-traditional deployment methods (internal only) | |
| Outbound | UDP | 123 | NTP, required when not using Amazon Time Sync Service |
