WHat do you mean on the wire? THe other side? Is the other side
setup to tunnel? How did you configure the outside IP'w with
gifconfig ? Need a tad more details to help you out.
the behavior you described below about the kernel adding routes
is correct as a 'gif' tunnel is a directly connect
interface. Most OS's do the same thing with directly connect
interfaces.
