title: TCP/IP using Socket Test 3.0 software
body: <p>I have 'Socket test v-3.0' software installed on two different PCs.
  Using it can create a TCP server on 1st PC and a TCP client on 2nd PC.</p>
  
  <p>When I connect both the PCs on LAN I can establish a connection &amp; can communicate between the Server &amp; Client.</p>
  
  <p>But, When I connect both the PCs to individual Internet connections (Using dongles having different ISPs), I couldn't establish the connection between the Server &amp; Client.</p>
  
  <p>How can I do that?
  Please help me out..</p>
