title: tcpdump for vpn tunnel
body: <p>I have two machines which are conected with vpn tunnel. I need to sniff the traffic (http requests) with tcpdump. I am using this command:</p>
  
  <pre><code>tcpdump -w log.pcap -s 64000 host
  </code></pre>
  
  <p>where host is my virtual ip, but I can only see the responses, not requests.
  How can I see http requests?</p>
