Three unimplimented solutions are listed on the web page you mention. I am aware of a simple, perhaps ugly, hack which works: establish two network addresses for the tunnel device. One is for the fake address when offline, and the other is of course for the assigned dynamic address. aaron@thud:~> ifconfig tun0 tun0: flags=8051<UP,POINTOPOINT,RUNNING,MULTICAST> mtu 1500 inet 206.114.185.47 --> 207.198.22.100 netmask 0xff000000 inet 10.0.0.1 --> 207.198.22.100 netmask 0xff000000 Unfortunately, this does not solve the problem of aliased packets failing to get through on the first try. That sure doesn't say much for the generality or robustness of this solution. However, if none of the other three options listed are implimented, people who really need that first packet to work could use this method.
