hello list,

I'm having trouble to establish an isdn connection.
Everything seem to work but somehow ippp0 tries to establish a ppp
connection via ipv6. This attempt (ipv6cp) is rejected by the peer.
After that, the ipcp pap authentication succeeds and I get an IP
(ipv4) but before the connection is established the connection is
closed. During dialing my console prints: "ipv6cp illegal up in state
req-sent" all the time.

Here is the debug log from ifconfig.
