UDP broadcast filters.

Mon Mar 16 14:39:24 UTC 1998

I've kept hearing about a UDP smurf floating around and I'd like to put up
a firewall to prevent it.  Can anyone give me any insight on how this is
done?  I don't understand enough about UDP, broadcasts or enough about
access-lists to create an effective one.  Can anyone give me some
pointers?
