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. --------------------------------------------------------------------------- This list is sponsored by: Norwich University EARN A MASTER OF SCIENCE IN INFORMATION ASSURANCE - ONLINE The NSA has designated Norwich University a center of Academic Excellence in Information Security.
