Dear list,

I'm setting a NEMO testbed using NEPL but I'm having some problems.
I followed the HOWTO by Romain KUNTZ, so my test scenario is basically the
same as the one presented in the HOWTO.


            MNN               Mobile Network Node (MNN)
             |::2        
   -------------------------  Mobile Network (NEMO-Link) [2001:1:1::/64]
       |::1
       MR                     Mobile Router (MR)
       |::2
   -------------------------  Home Network (HN) [2001:1::/64]
               |::1
    CN         HA             Home Agent (HA)
    |::3       |::1
   -------------------------  Internet [2001::/64]
       |::2           
       AR                     Visited Network Access Router (AR)
       |::1
   -------------------------  Visited Network (VN) [2001:2::/64]


Problems:
---------
1. When the MR (and the NEMO) moves to the Visited Network the MR sends a
Binding Update to the HA, but the HA doesn't send the Binding Acknowledgement
to the MR. In the NEPL debug the HA says that he is going to send the BAck,
but he doesn't. Even though, the tunnel is created by the HA and the MR. In
fact, because of the fact that HA doesn't send BAcks in response to BUs, the
MR allways creates the tunnel, even when he doesn't successfuly register with
the HA (because some error I provoked). Any knowledge about this!? Solutions!?

2. When I ping6 the MR from the HA (when the MR successfully registers with
the HA), the Echo Requests pass the tunnel and arrive at the MR, but the MR
doesn't reply to the HA. Also, I saw that I can't ping6 the HA from the MR,
"operation not permitted". Is it possible that my tunnel isn't bi-direccional,
but uni-direccional!? Solutions!?

3. Even when the NEMO is at home, I can't ping6 anything beyond the HA from
the MNN, although the MR has a default route pointing to the HA and the MNN
has a default route pointing to the MR. (Note: The MNN is a virtual machine
(VMware) inside the MR with host-only network interface - vmnet1.) If I
explicitly create a route, in the MR, to the Internet pointing to the HA, I
can reach the it from the MNN, but this isn't desired because it should be the
nemod to control the routes in the MR. Does anyone knows anything about
routing problems about this with VMware!?


Notes:
------
1. When the MR (and the NEMO) is in the Home Network (except for MNN that
can't reach Internet without a manual route) I have global IPv6 connectivity!

2. I'm using Fedora Core 6 Linux (with a 2.6.15 patched kernel).

3. "sysctl -a | grep ipv6 | grep forwarding" tells me that I have forwarding
activated in all interfaces.


All the help would be greatly appreciated!
I'm posting this in both Nautilus and MIPL mailing lists.

Thank you very much!
