Subject:  no IPv6 Routers present

Hi All,

i am working on a combined Firewall, means
2 Firewalls on one Personal Computer.

The first firewall is for my <ppp0> and
the second firewall is for <eth0> if i connect
through my Server to the internet.

However, if i plug off and plug in my network
cable, to change the connection from <eth0> to
<ppp0>, the connection to internet fails.
 From <ppp0> to <eth0> works, but than i can
not switch back because of a unkown connection
error.

<dmesg> prints out:
no IPv6 Router present

Ok maybe this is true. There is no IPv6 Router
in my lan, but why do my Kernel not switch back
to IPv4 ?

How can i correct this ?
I do not want to disable the whole IPv6 kernel/program
options.

Is this a Bug ?
