And? What the difference? For the P-t-P connection, there is not difference. There is only one destination, you can send the packets to: the ppp-server on the other side. Only for normal network-connections (eth0, ...), you have to tell the kernel, which host in the subnet he has to send the packets to, because usually there are many of them.
