Configuring DNS for Standalone Sentry
Configure DNS so that the Standalone Sentry instance on AWS uses DNS on the other side of the AWS tunnel by default. Configuring the DNS for Standalone Sentry is optional. You may need to configure the DNS for Standalone Sentry in some cases, such as, the backend resources that Standalone Sentry connect to are on premise.
Procedure

| 2. | Create a new DHCP Options Set. |
| - | Add the internal domain name for Standalone Sentry. |

The Standalone Sentry AWS instance in the VPC now defaults to using the DNS on the other side of the AWS tunnel by default.
