4in6 Tunnels

[hdav]

Hi,

I'm trying to get a 4in6 tunnel (i.e. IPv4 traffic tunnelled across an IPv6 network) going on an RPi running Raspbian.

I've loaded the ipv6 kernel module with:

Code: Select all

sudo modprobe ipv6

and then I'm trying to create the tunnel with:

Code: Select all

sudo ip -6 tunnel add tun1 mode ipip6 remote <remote address> local <local address>

but this give me the error:

Code: Select all

add tunnel ip6tnl0 failed: No such device

I get the same result with any of the other IPv6 tunnel types so I'm guessing there is a kernel module not loaded for that device type?

Some googling suggests there ought to be an ip6_tunnel and a tunnel6 module but Raspbian seems only to have the latter which I can load ok but that doesn't fix the tunnel creation error.

On a ubunutu box lsmod shows that both ip6_tunnel and tunnel6 are loaded (and the tunnel add works ok).

Can anyone point me in the right direction?

Regards,
Hugh

OK,
I decided to crosscompile the 3.6.11+ kernel and a few more modules that I needed anyway
to make that ipip6 tunnel statement work, load modules in the following sequence

Code: Select all

sudo modprobe tunnel6
sudo modprobe xfrm6_tunnel
sudo modpreobe ip6_tunnel

(without xfrm6_tunnel there were unresolved symbols in my syslog output)

I uploaded the module I compiled today and it works for me on

Code: Select all
