hi,

some firewalls (like checkpoint fw-1) have by-default open services, you can
detect firewall if this services or ports are open.

for example 256/18264/264 ports are open, this firewall is checkpoint fw-1.

also you can analyze tcp/ip fingerprints for firewall operation system
(*bsd, linux, solaris etc.)

good luck.

hi

We all know that, we can identify firewall using various  methods and
tools like "firewalk".
Is there any method or tool available which will remotely fingerprint and
enumerate rule base configured on the firewall?
