The [`destination`](/docs/connect/config-entries/service-defaults#terminating-gateway-destination) field of the `ServiceDefaults` Custom Resource Definition (CRD) allows clients to dial an external service directly. For this method to work, [`TransparentProxy`](/docs/connect/transparent-proxy) must be enabled.
The following table describes traffic behaviors when using the `destination` field to route traffic through a terminating gateway:
| External Services Layer | Client dials | Client uses TLS | Allowed | Notes |
| ----------------------- | ------------ | --------------- | ----------- | --------------------------------------------------------------------------------------------- |
| L4 | Hostname | Yes | Allowed | `CAFiles` are not allowed because traffic is already end-to-end encrypted by the client. |
| L4 | IP | Yes | Allowed | `CAFiles` are not allowed because traffic is already end-to-end encrypted by the client. |
| L4 | Hostname | No | Not allowed | The sidecar is not protocol aware and can not identify traffic going to the external service. |
| L4 | IP | No | Allowed | There are no limitations on dialing IPs without TLS. |
| L7 | Hostname | Yes | Not allowed | Because traffic is already encrypted before the sidecar, it cannot route as L7 traffic. |
| L7 | IP | Yes | Not allowed | Because traffic is already encrypted before the sidecar, it cannot route as L7 traffic. |
| L7 | Hostname | No | Allowed | A `Host` or `:authority` header is required. |
| L7 | IP | No | Allowed | There are no limitations on dialing IPs without TLS. |

You can provide a `caFile` to secure traffic between unencrypted clients that connect to external services through the terminating gateway.
Refer to [Create the configuration entry for the terminating gateway](#create-the-configuration-entry-for-the-terminating-gateway) for details.
Also note that regardless of the `protocol` specified in the `ServiceDefaults`, [L7 intentions](/docs/connect/config-entries/service-intentions#permissions) are not currently supported with `ServiceDefaults` destinations.

Normally, Consul services are registered with the Consul client on the node that
they're running on. Since this is an external service, there is no Consul node
to register it onto. Instead, we will make up a node name and register the
service to that node.
