Hi Mathieu,
Yep, it's entirely possible to start MN in foreign link and it works
very well over here.
Can you see any error in "dmesg" which could be related to your
traffic (eg. xfrm errors)?
Have you enabled IPsec in your configuration?
Also, don't hesitate to send an ethereal capture, and we'll have a look.

If it's possible to start a MN in a foreign network I have a problem
the. Because as I said, no Binding Update are send trough the MN's
interface (I sniff the traffic with ethereal). Therefore, HA can't
update is binding binfing cache..
On the contrary when I start the romaing in the home network alll is ok.

HI
You can start MN in a foreign network ... there's no limitation on
mip6d about it.

Hi everyone
I was wondering if it was mandatory to start the Mobile Node in the
home network.
I tried to initialize mip6d in the foreign network and these are the
debug messages :

What I understand from this log is that : the MN knows it is in a
foreign network and then tries to send Binding Update to the HA. If
I'm right, I didn't sniff any Bindig Update with Ethereal and the
binding cache of the HA is empty.
In RFC3775, it doesn't tell anything about the starting of a MN in a
foreign network, am I wrong??
Could anyone tell the way mip6d is implemented in this case??
Thank you
Best Regards
Mathieu
