Yeah I saw the same thing some time ago. At least I thought I
did. It turns out that the "temporary" or kernel generated routes
do not show up when you issue a "route" or "netstat -r" command.
The newest versions of the netutils [will] take care of this.
For now, just do a "cat /proc/net/rt_cache" and you will see
that the route is there.
