I've had a problem with a udp connection being setup before DNAT, 
occurred. See "where are my udp packets going?" Nov 15, 2008.

So just before setting up DNAT I'd propose to run:

conntrack -D -p	udp --dport 4569

but the user guide says this "blocks" the connection. I only want to 
flush/empty it, and let it start again with DNAT working.

Does this do it? Or some other command?
