Hi Min, I think the problem is that the xdmcp protocol requires a special helper module to add the necessary connection expectations, since it appears to open random connections, like ftp for instance. This raises an interesting question: Here: http://cvs.netfilter.org/cgi-bin/cvsweb/netfilter-extensions/helpers/xdmc= p/ is some work on a conntrack helper/nat module by Hojae Lee, apparently. I've never heard any noise about this, the code is not available in standard patch-o-matic, and I am also wondering what the whole /netfilter-extensions CVS directory is all about ? Perhaps Harald knows more about this...
