<p>I already set the externalIP and port for this service, but it seems didn't work, I wonder what's wrong with the configuration, thanks !!</p>

<p>To have an external access to a NodePort service the node should have a public ip address assigned to it. 192.168.96.10 is a private ip address.</p>
<p>IANA has assigned the following 3 ip ranges for private network -</p>
<pre><code>Address ranges to be use by private networks are:

    Class A: 10.0.0.0 to 10.255.255.255
    Class B: 172.16.0.0 to 172.31.255.255
    Class C: 192.168.0.0 to 192.168.255.255
</code></pre>
