title: Ping not working from tap interface attached to bridge interface with ip on same subnet as that of bridge to outside
body: <p>My requirement is to create a multiple tap interfaces, each with ip address on same subnet. </p>
  
  <p>I tried this by creating a bridge </p>
  
  <pre><code>               br0 (192.168.1.199)
       ___________|_____________________________________
       |                    |       |      |      |     |
     eth0                  tap0    tap1   tap2   tap3   tap4
                  (192.168.1.150)  (.151) (.152) (.153) (.154)
  </code></pre>
  
  <p>I need all the tap interface be reachable from external PC. When i ping from tap0 to external computer say 192.168.1.200</p>
  
  <pre><code>ping -I tap0 192.168.1.200 -- the ping is not going through. 
  </code></pre>
  
  <p>But when i ping from 192.168.1.200 to 192.168.1.150 (tap0) it is working, but i get the mac address of the bridge (br0)</p>
  
  <p>I have two problems:</p>
  
  <ol>
  <li>How to ping from tap interface to external</li>
  <li>How to get the mac address of the right tap interface, when pinged from outside. </li>
  </ol>
