I can ping from client ppp server and other hosts residing on the same ethernet in the same subnet can too . Also I can reach 10.0.0.1 client from ppp server and these hosts. I understand that while ppp-server has direct route to the client and other hosts on the ether have this ppp-server as defaultrouter they can reach client. But hosts from outside this subnet, such as host that is defaultrouter for my ppp-server doesnt know how to reach 10.0.0.0/24 hosts and they sends their repleys to their defaultrouters - checked with tcpdump. And my question was why ppp doesnt alias the packets from unregistered networks. I think ppp have to works like natd in this case. I.e. every packet from unregistered have to be resent to destination by ppp with its own addr. And answers have to be retransmitted to the client. Isnt it?
