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.
