The reason I ask is that a > connection is made but no route is able to occur. PPPoE connection as in any other PPP uses not DHCP protocol but uses IPCP protocol to NEGOTIATE connection parameters. Each side of connection can try to give some parameters to other and each other can take/allow them or not. What about same IP - you can try to look in your PPPoE log for IPCP negotiation process and try to find what side offers using of this IP. -- Alexander Motin
