title: Adding a rule in iptables in debian to open a new port
body: <p>I am trying to open port 3306 in iptables in my Debian System to allow access to MySQL server. For which I entered this command:</p>
  
  <pre><code>root@debian:/# sudo iptables -A INPUT -p tcp --dport 3306 ACCEPT
  root@debian:/# iptables-save
  </code></pre>
  
  <p>I entered the new connection and it has been saved in iptables as I can see the new rule in iptables list genereted by iptables-save command.</p>
  
  <p>However, this debian system is running on a VM over Windows7 and I'm not able to telnet from Windows to this port. Not sure where I am supposed to check for the solution to this problem.</p>
