title: Port Forwarding UDP video stream from two cameras
body: <p>I am getting UDP video streams from two cameras with different IP addresses to my laptop. However, they stream onto the same port 8554. I can not change the streaming port in the cameras. However, when I try to capture video, they are scrambled because of the same port.
  I tried to forward one of the streams to different port using iptables.</p>
  <pre class="lang-sh prettyprint-override"><code>iptables -t nat -A PREROUTING -p udp -d 192.168.1.10 --dport 8554 -j DNAT –to-destination 192.168.1.10:554
  iptables -A FORWARD -p udp -d 192.168.1.10 --dport 554 -j ACCEPT
  </code></pre>
  <p>However, this is not working. Am I missing something here? Is there any other way to achieve this?</p>
