Dear Mathieu,
After having taken a look at the output of "ipsec look", I am not clear
if I understand what you want to do:
ipsec0->eth0 mtu=16260(1500)->1500
Destination Gateway Genmask Flags MSS Window irtt
Iface
192.1680.0.0 0.0.0.0 255.255.255.0 U 0 0
0 eth0
192.1680.0.0 0.0.0.0 255.255.255.0 U 0 0
0 ipsec0
This tells me that you have a kernel with FreeSWAN KLIPS compiled and
loaded. FreeSWAN KLIPS does not support IPv6. For having running IPsec
for IPv6 use either a 2.4.x (x>24) with ipsec backport or a recent 2.6.x
kernel. Don't compile those kernels with KLIPS support as it is not
possible to have both KLIPS and kernel ipsec!!!!
All information that I have given in my previous mails assumed that
kernel 2.6.x and Openswan 2.1.x is used. The patches Mikael provided
assumed also that kernel ipsec is used and *not* KLIPS.
Hope this helps,
Gerhard

Hi Gerhard,
First, thank you for help, that's very nice....
I've changed my config, but I think it doesn't matter. The
problem is before...
I've tried to set up an automatic keying connection (in
ipsec.conf with command ipsec auto --up connection) , but when I put
ipv6 adress, it doesn't recognize the connection....
"021 no connection named "v6" "
I'm not surprised...
When I start the ipsec service, the "ipsec look" command shows :
ipsec0->eth0 mtu=16260(1500)->1500
Destination Gateway Genmask Flags MSS Window
irtt Iface
192.1680.0.0 0.0.0.0 255.255.255.0 U 0 0
0 eth0
192.1680.0.0 0.0.0.0 255.255.255.0 U 0 0
0 ipsec0
and when I execute ifconfig, it shows me the ipsec0 virtual
interface, with both ipv4 adress and ipv6 local link but no the ipv6
global one....
I'm trying now to set up a manual keying connection to test
it...
Well it doesn't work..
What do you think ?
Matt

Hi Mathieu,
at first look, your global IPv6 address configuration seems to
be not correct. According to your ifconfig output, the prefix length is
0. A prefix length of 64 seems to me more appropriate. Second, the
prefix length for your link local address is 64. That is quite wired as
I would normaly assume to be it 10. Third, as Mikael already pointed
out, it could well be that Pluto does not like the fact that no IPv4
address is assigned to the interface. If you only want to work with
IPv6, it does not hurt to have an (e.g. private) IPv4 address assigned.
How do yo (in the current example) try to setup your SA? (1)
With configuration in ipsec.conf (after having applied Mikaels patches)
or (2) with a manual command to Whack and Pluto. In both cases, we would
need to have the used configuration to help you further.
Cheers,
Gerhard

Hi,
I've been trying for days to set up OpenSWAN with IPv6
support...
So, I'am using the 2.1.1 version patched with Mikael
Magnusson'patch..
It doesn't seem to work with ipv6 :,-(
Here's my config
