For Checkpoint, use nmap and do a TCP and OS detection scan. 
If they are 
doing one-to-many NAT the machines will be detected as 
"behind a Checkpoint 
Firewall-1 4.1 SP2 Server" or whatever. The firewall itself 
is likely to 
have some combination of  TCP ports 256-259, 264-265 open for 
management,
auth, key exchange, etc. 

What criteria is nMap using? What would the result be if a) the
well-known-Checkpoint-ports are closed, and b) the default TTL has
been monkied with? (Not you, Doug)

Regards,
Frank
