Kubernetes: Can not reach service with master IP PORT

I have a kubernetes cluster with 1 master and 1 node, when i create a SVC for a deployment , i can see listening ports on node and master but i reach the service only from node (telnet NODE-IP PORT) but not by MASTER-IP and PORT .. I dont know how to trace this issue ..
Created Services with NodePort .
Master Int ip
Node Int ip

[nava@kmaster ~]$ kubectl describe svc nginx
Name: nginx
Namespace: default
Labels: name=nginx
Annotations: <none>
Selector: app=nginx
Type: NodePort
Port: http 80/TCP
TargetPort: 80/TCP
NodePort: http 30080/TCP
Session Affinity: None
External Traffic Policy: Cluster
Events: <none>

telnet 80 << on kmaster failed
telnet 80 << on knode passed

kmaster does not forward traffic to knode

Any Suggestion
