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 with a TTL one greater then 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 host does not allow the traffic, it will likely drop the packets on the floor and it will see no response.

Firewalking is a technique developed by Mike Schiffman and David Goldsmith that employs traceroute-like techniques to analyze IP packet responses to determine gateway ACL filters and map networks. Firewalk the tool employs the technique to determine the filter rules in place on a packet forwarding device. The newest version of the tool, firewalk/GTK introduces the option of using a graphical interface and a few bug fixes.
