Re: RE: Re: Penetration Testing a Firewalled Network

[kratzer.jason () gmail com]

I do know what is running on the internal network.  I suppose the purpose of this is to audit the level of security 
provided by the firewall itself.  I have already found vulnerabilities resident in the VPN and Webserver which would 
allow me access to the internal network but I would like to see, for personal interests as well as to demonstrate the 
level of security provided by the firewall, if there was any way to enumerate internal network information due to 
poorly configure filters.  Since the beginning of this audit I have began research into packet manipulation in order to 
blindly discover available internal hosts and would simply like to know if it was possible to do so across the internet 
without access to a dmz zone.
