First of all, thank you for kind answers...
I'm now making xdmcp conntrack/nat module... I must change the data pointed by iphdr in conntrack_helper_function. I tried to change the data, but it's not changed... Is conntrack helper module receiving copy of the packets? Then is there any solution that I can change the data of the packets in conntrack helper module? XDMCP use udp.... There is IP, display no in data of datagram... So I changed these to masq IP, masq display no.. I tried to change this, but it's not working... When I was trying this in kernel ver 2.2, it's working.. If anybody knows, please let me know.. Thank you.... Have a nice day~~ Sincerely yours... Hojae Lee --MIME Multi-part separator--
