Hi,
that with VM-Ware could be a problem. Try to boot from the Live-CD
directly and then do the scan. That is what you told. You could give
Sentoo a try. Its also a Live-CD based on Gentoo. They've build a lot of
security tools into (actualy almost everything that I know and use daily).
One more suggestion. Try to scan the FW from the internal network or
dial-in with VPN and scan internal interfaces and try to use the nmap
option -T in polite or other mode. If you have still any questions, feel
free to post.
Kind regards,

Hello,
thanks for Your answer.
So here are some more information:
I'am trying to scan the firewall (Watchguard X700) of my company from home
for securityreasons. So I know which ports are open, because I'am
administering the firewall.
I use the BackTrack 3.0 (remote-exploit.org) live linux cd. This is based
on slackware. Kernel 2.6.156. with Nmap 4.03.
On the Watchguard X700 all intrusion prevention features are disabled. So
"Block SYN Flod Attacks" is also disabled. The firewall is not blocking me
because I can do normal Connect() scans after a SYN-Scan and with the
Connect() scan the open ports 80 and 443 are correctly found.
Maybe VM-Ware (Windows) is the reason? I've run BackTrack in a vm (direckt
access to nic) under Windows. What I will try this evening is to boot the
notebook directly with the BackTrack-CD and connecting directly with my
ISP. Then performing a SYN-Scan again. Maybe then I will get better
results.
I will then post my result here.
