Setting the label `traefik.http.services.xxx.loadbalancer.server.port`
overrides that behavior.
??? example "Specifying more than one router and service per container"
Forwarding requests to more than one port on a container requires referencing the service loadbalancer port definition using the service parameter on the router.
In this example, requests are forwarded for `http://example-a.com` to `http://<private IP of container>:8000` in addition to `http://example-b.com` forwarding to `http://<private IP of container>:9000`:
```yaml
version: "3"
services:
my-container:
# ...
labels:
- traefik.http.routers.www-router.rule=Host(`example-a.com`)
- traefik.http.routers.www-router.service=www-service
- traefik.http.services.www-service.loadbalancer.server.port=8000
- traefik.http.routers.admin-router.rule=Host(`example-b.com`)
- traefik.http.routers.admin-router.service=admin-service
- traefik.http.services.admin-service.loadbalancer.server.port=9000
