Re: Server blocks access of IP after nmap scan

["Littlefield, Tyler" <tyler () tysdomain com>]

hello:
I'm curious what prompted this? How did the firewall block ports from 
being scanned by nmap?
Also:

I'd think this was pretty easily solved? If you have two NIC cards at 
least, you can limit everything for class_A/B/C to that specific 
interface, drop
everything on the external interface coming from class a,b,c or 
loopback. But it'd still be possible I suppose to spoof an address when 
you sent off a
packet to get someone else blacklisted; how do people work against that?
