Use the LOG target.
However, if this is your firewall host toward Internet, are you sure you
want to log *everything* that is dropped? There are so many worms and
automatic scanning tools out there that your logs will get *huge* with
nothing but crap very fast. This is especially true for Windows
specific TCP and UDP ports. Anything that might be interesting will get
completely lost in all that noise.
