I have a problem with accessible my service from outside. First of all, here is my conf yaml files:

nginx-pod.yaml

apiVersion: apps/v1
kind: Deployment
metadata:
  name: my-nginx
  namespace: development
spec:
  selector:
    matchLabels:
      app: my-nginx
  replicas: 2
  template:
    metadata:
      labels:
        app: my-nginx
    spec:
      containers:
      - name: my-nginx
        image: nginx:1.7.9
        ports:
        - containerPort: 80

nginx-service.yaml

apiVersion: v1
kind: Service
metadata:
  name: nginx-service
  namespace: development
spec:
  type: LoadBalancer
  selector:
    app: my-nginx
  ports:
  - name: http
    port: 80
    targetPort: 80
    protocol: TCP

metallb-config.yaml

apiVersion: v1
kind: ConfigMap
metadata:
  namespace: metallb-system
  name: config
data:
  config: |
    address-pools:
    - name: default
      protocol: layer2
      addresses:
      - 51.15.41.227-51.15.41.227

Then i have created the cluster. Command kubectl get all -o wide prints:

NAME READY STATUS RESTARTS AGE IP NODE NOMINATED NODE pod/my-nginx-5796dcf6c4-rxl6k 1/1 Running 1 20h 10.244.0.16 scw-7d6c86

Everythink is fine, also kubectl describe service/nginx-service prints:

Name:                     nginx-service

Curl command inside master server curl 51.15.41.227 prints Welcome to nginx blablabla. Next i tried to open from another network, it doesn't work, however i added node port it works curl 51.15.41.227:30883. All this i did on a bare-metal. I expected to happen curl 51.15.41.227 from external host should reach result. What did i do wrong?
