I probe my firewall with the NMAP scanner, but I think this is a simple task. I´d like to kown, how my firewall is secure. I need more tools and concepts. Thanks to all people on this list. I´m always reading this list and its very helpfull. Zangao - [To unsubscribe, send mail to majordomo@lists.gnac.net with "unsubscribe firewalls" in the body of the message.]
