75=head1 SYNOPSIS
76
77B<setup_bridge.pl> Connects the established ssh tunnel (a tap interface) to
78a local interface through a bridge interface.  Traffic on the local interface
79will cross the network over the ssh tunnel and be released onto the net via a
80symmetrical setup on the peer.
81
82The interface to attach can be given either by its interface or an address/DNS
83name to reach.  In either case, all IP addresses are removed from the
84bound interface.
