On second thought, maybe a firmware update will help see forinstance: http://support.dlink.com/products/view.asp?productid=DI%2D614%2B note that the release notes for version 2.33 say older versions crash after 1000 NAT entries (ouch, at the moment, my linux box says I have greater than 500 tracked connections, and I'm not doing anything.) So... Try a firmware update first --Matthew
