Firewalk is a network auditing tool that attempts to
|
|
|
|
|
determine what transport protocols a given gateway will
|
|
|
|
|
pass. Firewalk works by sending out TCP or UDP packets

2000-12-23 04:05:41 +01:00
|
|
|
with a TTL one greater than the targeted gateway. If the
|
1999-06-09 03:25:02 +02:00
|
|
|
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 host does not
|
|
|
|
|
allow the traffic, it will likely drop the packets on the
|
|
|
|
|
floor and we will see no response.
