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? -- Regards, Jason A.
