Red Squirrel said:Easiest way is to just get a hardware firewall, a cheap router will do the trick, since your external IP will point to the router so if the router is properly configured, not much can be done to it, your machine will be behind it and even if it's ports are open, they can only be accessed from your network, unless you forward them to a machine...
...But a sofware firewall like ZA should do the trick as well, but in my opinion a router is better, and leaves room for future expansion, and that's a nice word for network people.
Yeah I run a lovely little Cisco Router and ZoneAlarm, and we all know Cisco ARE the network peeps
Personally, I wouldn't have kept the attack going this long PERSONALLY, sitting there myself. They guy had probably activated the attack by signalling his zombie machines, which are going to keep running the attack until he signals them to stop. He's probably forgot to tell them to stop!
If so, it may be a while before the zombies give demise a break, or until this guy want to target someone / thing else...
