  <p>There i have set the firewall rule also on my Linux machine as given command </p>
  
  <p><code>(/sbin/iptables -L INPUT | /bin/grep 192.168.xxx.x | /bin/grep tftp || /sbin/iptables -I INPUT -p UDP -i eth0.100 -s 192.168.xxx.x --dport 69 -j ACCEPT) &gt; /dev/null 2&gt;&amp;1</code><br>
  <code>/sbin/iptables -A INPUT -i eth0.100 -s 192.168.xxx.x -p udp -m state --state NEW,ESTABLISHED,RELATED -j ACCEPT &gt; /dev/null 2&gt;&amp;1</code><br>
  <code>/sbin/iptables -A OUTPUT -o eth0.100 -s 192.168.xxx.x -p udp -m state --state ESTABLISHED,RELATED -j ACCEPT &gt; /dev/null 2&gt;&amp;1</code>  </p>
