Hi
I don't know if this is intentional or a bug, but if ifconfig is used to
configure a point to point device, such as 'tun' or the newer 'gif' devices,
then the kernel insists on installing a route where the destination is the
end point of the tunnel, the gateway is the source of the tunnel and the
interface is the device itself. I have checked this in version 3.2+KAME,
what I a using, and also on version 4.1. The effect of the above is that the
packet that uses the tunnel will never appear on the wire.
Here is an output
the_swamp# ifconfig gif0 132.146.115.164 132.145.113.1
the_swamp# netstat -rnf inet

I am also interested in using gated with point to point tunnels, but gated
also insists on doing the above for point to point links.
I thank you in advance for any advice you may have.
