A quick google of the insmod messages above reveals that this message
occurs when the kernel has not been built with bridge support. So
logically, one concludes that the bridge module was not built as part of
the Unslung 6.8-beta kernel, but must be from some other kernel.
It turns out that the 6.10 kernel *was* built with bridge support, so
the module installs -- but the result is an immediate kernel panic and
crash. This would seem to explain why the 6.8 kernel didn't support the
bridge module, it very probably failed and was removed. Clearly it was
not tested when it was re-enabled in the 6.10 kernel.
In any case, it doesn't work on either 6.x release of Unslung. I'd
suggest that you stick with the tun driver (which works), or switch to
SlugOS or Debian.

But i went faster, shame on me. I installed Unslug 6.10 and I had what

I have trouble with ip_forwarding. I get that !!!

How can I get permission for that ?

difficult if you need to get anything but Microsoft's vision of TCP/IP
is working. But I understand your point, and I have to note that the
various alternate firmwares for the router-type devices usually have all
the bridge and routing stuff thoroughly tested, well integrated, and
some of them even have a nice web-based GUI on them. That said, I run a
tun-based openvpn connection on one of my Unslung 6.8 NSLU2's, and it
works very nicely.

"cat /proc/sys/net/ipv4/ip_forward", but I think you want to set it.
Here's the startup file I use to start openvpn on my system
if [ -n "`pidof openvpn`" ]; then
/bin/killall openvpn 2>/dev/null
# load TUN/TAP module
# enable IP forwarding
echo 1 > /proc/sys/net/ipv4/ip_forward
# startup VPN tunnel in daemon mode
/opt/sbin/openvpn --cd /opt/etc/openvpn --daemon \
--log-append /var/log/openvpn.log \
Set up the server.conf file so that it has the correct addresses, of course.

Thank again, Mike,
I have found that my trouble to use the VPN was due to the router used
juste after the Slug. It was not as configurable as I though and the
IP frame comming from the VPN through the slug were blocked.
So I installed on the Slug a proxy, and tada, now it work. It is not
very fast, but fast enough for what I want.
My config is:
EEEPC <-> Samsung mobile phone <----> Internet proxy Bouygue Telecom
<---> Router ADSL ADSL provided <-> NSLU2
the VPN is mounted between EEEPC and SLUG through my mobile phone
EEEPC has web access through my slug proxy
Result: illimited internet access with edge bandwith...
I have to read a little bit the documentation of the proxy in order to
be able to connect to my email account using pop and smtp protocol.
But today, i can use the webserver going through the VPN and the proxy.
Perhaps I will install a web server on the slug, ... wait and see.
It's a very good tiny toy...
