Unable to access external network from k8s Pods


I am getting one weird issue while deploying Cluster on Kubernetes.

Some background details:

I have deployed Kubernetes Cluster using kubeadm-1.10.5 on my on-prem hardware with Weave plugin.

Master : Centos 7.3
Node1 : Centos 7.3
Node2 : Centos 7.3
Node3 : Centos 7.3
Node4 : RHEL 7.2 Kernal `3.10.0-327.el7.x86_64`
Node5 : RHEL 7.3 Kernal `3.10.0-514.el7.x86_64`

Now everything works fine except on Node4. On this node4 I have successfully deployed all the kube-system pods and my application Pods, but the only issue which I am facing is any pod launched on node4 is unable to access/ping any external IP address.
