62tap/bridge combo.

79=head1 SYNOPSIS
80
81B<setup_bridge.pl> Connects the established ssh tunnel (a tap interface) to
82a local interface through a bridge interface.  Traffic on the local interface
83will cross the network over the ssh tunnel and be released onto the net via a
84symmetrical setup on the peer.
85
86The interface to attach can be given either by its interface or an address/DNS
87name to reach.  In either case, all IP addresses are removed from the
88bound interface.
