title: C# Sniff Packets from another computer on the same Network
body: <p>I've looked around at various C# Packet Sniffing tutorials and have built one that can parse packets sent to and from my computer.  This is awesome, but I haven't found <b>anything</b> that relates to intercepting packets from another computer (obviously on the same network), e.g. from a different computer to a router.</p>
  
  <p>Am I correct in thinking that any packets sent by a computer are visible to, not only the router, but any other computers on the same network?  If this is the case, does that not mean that intercepting these packets is something we can do in C#?</p>
  
  <p>To those who are desperately copying and pasting links to Wireshark etc. I appreciate your time but this is more of a learning experience for me, so I'd like answers relevant to C# if possible!</p>
  
  <p>In summary, how can I intercept packets in C# that don't concern my computer?  E.g. From my laptop to my router?</p>
