Description : attempts to determine what rules in a remote firewall.
Firewalk is an active reconnaissance network security tool that attempts to
determine what layer 4 protocols a given IP forwarding device will pass.
Firewalk works by sending out TCP or UDP packets with a TTL one greater
than the targeted gateway. If the gateway allows the traffic, it will
forward the packets to the next hop where they will expire and elicit an
ICMP_TIME_EXCEEDED message. If the gateway hostdoes not allow the traffic,
it will likely drop the packets on the floor and we will see no response.
