Hi , Thanx for your reply 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 #################################################################### I have a setup where the tftp server is inside the firewall. 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 ? Otherwise i hope, it is not a solution that i will open all port related to UDP in the firewall. ######################################################################### Regards, lingu On Mon, Jun 9, 2008 at 5:28 PM, lingu <hicheerup at gmail.com> wrote: > Hi, > > I have a setup where the tftp server is inside the firewall. > > Now the issue is tftp client send request on dynamic udp port.
