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.
