Re: nmap in vmware

There can be a multitude of things affecting you here.
1. Good that you notify these folks. Just out of curiosity, why would
you perform vul assesment from behind a firewall?

2. The Framework could be sending over dozens of different ports, most
of which are probably blocked as incoming at the firewall, even if they
are part of an established session. They could also be blocked as
outbound, again, depending on ruleset.

3. I'm not sure if you are referring to the source or destination port
here. The source port really wont matter that much if the outbound rules
on your firewall are wide open. If the firewall is watching outbound
connections, then yes, you need to use ports that the firewall will
tolerate. If you are referring to the destination port, then you must
use the default port of the service that is being exploited. (assuming
the target system is using default ports). Its important that you use
these ports because that is how the target OS is determining what
services to pass the network request to.

4. This almost seems as though you aren't fully establishing a
connection. (the handshake process isn't successful)

5. The result of the exploit will depend on a.) whether or not it was
successful and b.) what payload you are using in conjunction with the
exploit.

Hope this helps
