Rather than worrying about what to do with these probes, you could upload your logs to either »
www.dshield.org or »
www.mynetwatchman.com. By doing that, you will be providing a valuable service to these sites and to users of the Internet as a whole, and you won't have to be concerned about which ISPs need to have a message sent to them. These great sites take care of that and because it comes from an organized respected site such as these, if an ISP is going to pay attention, they will more to them than you and I as individuals.
Btw., you will see lots of probes, to 137 and many other ports. If they're blocked, your firewall is doing its job.
