hello:I'm curious what prompted this? How did the firewall block ports from being scanned by nmap?
Also:>Good security defense, except if you try to find a way to spoof the ip =).
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? On 5/18/2011 12:22 PM, amon.amarth9 () gmail com wrote:
I solved the problem - I just used the nmap firewall/IDS/IPS evasion options and I specified fragmented packets, all together with different scan method than the usual SYN scan. Anyway the protection mechanism on the server is pretty good I think, even if you try to connect on some port that is not open it bans your ip address.
