You get the same results if the default Checkpoint ports are closed. You still need to find one or two open ports, but they don't have to be on the firewall itself. The giveaway is in how the headers are rewritten for one- to-many NAT. Frank Knobbe [FKnobbe () KnobbeITS com] wrote: 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?
