I have had an ASL box up and running for the last 2 weeks and for the first time today I got a notification message from ASL that I had been portscanned.
How serious is this? What is the best way to monitor/action this type of event...
The portscan some how managed to get the IP address of a machine on the "Private Network" behind the firewall - In my rules, all incomming traffic is denied access except for HTTP and FTP to a DMZ network of which is a different Private Network Address (192). How can I stop this happening?
