So it's not as simple as ignoring all interfaces except the one given in '-i' ?

No.

No.

Attached file is a testcase using 'nemu' ( http://code.google.com/p/nemu/ ), but I couldn't reproduce the issue.
Then I retried on the real router (replacing radvd by dnsmasq) and again I failed to reproduce the issue.

I must have done something wrong but I have no idea what.

Thank you a lot for your help.

Regards,
Julien
