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.

Regards,
Sai.

iptables-apply(8)					      System Manager's Manual						 iptables-apply(8)

NAME
iptables-apply - a safer way to update iptables remotely SYNOPSIS
iptables-apply [-hV] [-t timeout] ruleset-file DESCRIPTION
iptables-apply will try to apply a new ruleset (as output by iptables-save/read by iptables-restore) to iptables, then prompt the user whether the changes are okay. If the new ruleset cut the existing connection, the user will not be able to answer affirmatively. In this case, the script rolls back to the previous ruleset after the timeout expired. The timeout can be set with -t. When called as ip6tables-apply, the script will use ip6tables-save/-restore instead. OPTIONS
-t seconds, --timeout seconds Sets the timeout after which the script will roll back to the previous ruleset. -h, --help Display usage information. -V, --version Display version information. SEE ALSO
iptables-restore(8), iptables-save(8), iptables(8). LEGALESE
