   1. A trap for catching flies.
      [1913 Webster]

   2. (Bot.) A plant (Dion[ae]a muscipula), called also
      Venus's flytrap, having two-lobed leaves which are
      fringed with stiff bristles, and fold together when
      certain sensitive hairs on their upper surface are
      touched, thus trapping insects that light on them. The
      insects so caught are afterwards digested by a secretion
      from the upper surface of the leaves. The plant is native
      to North and South Carolina, growing in bogs.
      [1913 Webster]

firewall machine
flytrap

    A dedicated gateway machine with special security
   precautions on it, used to service outside network, especially
   Internet, connections and dial-in lines.  The idea is to
   protect a cluster of more loosely administered machines hidden
   behind it from crackers.  The typical firewall is an
   inexpensive microprocessor-based Unix machine with no
   critical data, with modems and public network ports on it, but
   just one carefully watched connection back to the rest of the
   cluster.  The special precautions may include threat
   monitoring, call-back, and even a complete iron box
   keyable to particular incoming IDs or activity patterns.

   Firewalls often run proxy gateways.

   Synonym flytrap, Venus flytrap.
