FF 647 ,

    This is kind of hard to do because you dont really know the subnet they
are using on their internal lan ( 10.* , 192.168.* or 172.16.* ) so the
worse part is to "guess" where they have the internal web servers. Some time
ago i asked myself this same question and i got to this answer :

        a ) configure proxychains to use the netcache
        b ) run : proxychains nmap -sT -sV -p80 -P0 192.168.1-15.1-50

    Also , netcache can be configured to retrieve only external web pages if
this is the case , i dont know how to bypass that.
    Hope this helps .

Cheers ,

Andres Riancho

Does anyone know of a way to test a netcache to see if
it will return content from web sites on an internal
network -- intranet sites that would otherwise not be
viewable by the public? Any info would be appreciated
as we are investigating techniques to simulate
Internet based attack vectors against our reverse proxy.
