Yeah, well, in all my readings and largely from the mail on this list, I've come to the conclusion that Snort definitly won't give me iptable-functionality on a windows box. My solution is one I should've done a while ago: start using linux. Of course, thats much harder than it sounds, but we'll see how it turns out. Thanks to the list for all the help.

I should probably add that the only two ways I know of making snort into an IPS; is by either using snort-inline, which would require IPTables (and this is a windows question) or using "flex response" (not sure if this comes with the windows version of snort), the downfall of flex response is that is just sends an RST packet to break the connection (this however does not stop the attacker from re-connecting) also, you would have to write your own rules such as: alert tcp $EXTERNAL_NET any -> $HTTP_SERVERS 80 (msg:"WEB-IIS CodeRed v2 root.exe access"; flags: A+; uricontent:"scripts/root.exe?"; nocase;resp:rst_snd;) (you can see the rst_snd at the end) but, as "shrek-m" and I (in my earlier email) said, snort cannot really be used as a firewall.

Why/why not? For those who are against using it as a firewall, again, why?"snort" iirc is a ids/ips and no firewall http://www.snort.org/ eg. "iptables" iirc is a firewall and no ids/ips http://iptables.org/ -- shrek-m
