You are making sense and I have seen the same thing. NMAP can't identify the servers behind the PIX. That's a good thing.
Yes, I agree with you. But then, it also makes PIX identification easier.
I am not sure how you identify the PIX. How do you fingerprint servers when you don't know what the servers are or if they are behind a PIX?
It was easy this time. If the PIX has the "fixup protocol smtp" enabled it would act as a "proxy" for smtp connections. The banner you would see then is something like this: 220 ********0********************************************0*2******00 ***************2******200***0********0*00 About the servers, IIS 5.0 was kind enough to provide me some info about the system :) Cheers Fernando -- Fernando Cardoso - Security Consultant WhatEverNet Computing, S.A.
