Add blacklist to your external interface (interfaces file)
Add the ip to the blacklist file.
You can ban the ip totally, or just for certain protocols.
Read the comments in the blacklist file.
Then do shorewall reastart.
Or it might be in the faq.
But why do you think you need this at all
if you are behind a shorewall firewall?
Why would you have any ports open to the
net that blaster could use?
