## Native Load Balancing
By default, Traefik sends the traffic directly to the pod IPs and reuses the established connections to the backends for performance purposes.
It is possible to override this behavior and configure Traefik to send the traffic to the service IP.
The Kubernetes service itself does the load balancing to the pods.
It can be done with the annotation `traefik.io/service.nativelb` on the backend `Service`.
By default, NativeLB is `false`.
!!! info "Default value"
Note that it is possible to override the default value by using the option [`nativeLBByDefault`](../../providers/kubernetes-gateway.md#nativelbbydefault) at the provider level.
```yaml
---
apiVersion: v1
kind: Service
metadata:
name: myservice
namespace: default
annotations:
traefik.io/service.nativelb: "true"
spec:
[...]
```
