Ubuntu Problem with iptables while doing tftp.

Hi all,

I have a problem. I have iptables enabled in my ubuntu system on which tftp server is configured. Now when I try to do a tftpget from another ubuntu 32-bit machine, file transfer is not happening. But, when iptables are disabled, everything is fine. I heard that some ip_conntrack module is required for tftp to work with ip tables enabled. Can you help me?

Thank you in advance.
