Hi ,<br><br>&nbsp;Thanx for your reply&nbsp; but my query is different already ip_conntrack_tftp is loaded in my centos . TFTP is working fine now ,but i want to toghten more security on iptables.Right now all of my udp port is opened, i dont want to do that .see my previous mail below<br>
<br>####################################################################<br>I have a setup where the tftp server is inside the firewall.
<br>
<br>Now the issue is tftp client send request on dynamic udp port. Can 
anyone give some idea, how i can bind the fixed port for client udp 
requests ? 

<br>Otherwise i hope, it is not a solution that i will open all port related 
to UDP in the firewall.<br>#########################################################################<br><br>Regards,<br>lingu<br><br><div class="gmail_quote">On Mon, Jun 9, 2008 at 5:28 PM, lingu &lt;<a href="mailto:hicheerup@gmail.com">hicheerup@gmail.com</a>&gt; wrote:<br>
