    Gateway portscanner.  This version was written using libnet 0.8c and
    libpcap 0.4a5.  Firewalk version 0.7d and above will not work with
    libnet older than 0.8c and below.

----------------

Version     Released        Changes
-------------------------------------------------------------------------------
    0.8:    12.xx.98        Corrected the handling of unreachables and expired
                             messages.  Previously the program could get TTL
                             expired and unreachables confused when a gateway
                             would proxy responses for hosts with unreachables. 
                             It should handle these better now.
                            Cleaned up some aesthetics.
