Depending on the linux kernel you are using.. this is a 'known' bug. Red 
Hat Linux for the 7,8,9 series has a patch from netfilter experimental 
that does not let go connections. There is also another kernel version 
that seems to have this issue (2.4.18?) but I cant remember which one it 
was. Putting on the latest 2.4.x kernel with a clean netfilter patch 
fixed the problem on our boxes.
