The situation: A linux box connected to a DSL Modem, on the other side is a Cisco LNS wh= ich terminates the PPP session (actually L2TP). I have control over both ends. When I have net.ipv6.conf.all.forwarding set to 0 then the ppp Interface = gets a IPv6 address from the Cisco via IP6CP. When I have net.ipv6.conf.all.forwarding set to 1 them the ppp Interface = does not get an address, it has only a normal link local address. When I start the ppp session with forwarding set to 0 I can ping out and = there exists a default route to ppp0 , then I switch forwarding to 1 the default route disappears and therefore routing does not work any long= er. Is this a known behaviour ? Or am I doing something the wrong way ?
