Tried your tun.ko:

# insmod /sdcard/tun.ko
insmod: init_module '/sdcard/tun.ko' failed (Exec format error)

I have the same problem trying to run openvpn on Droid 
2.2.20.A955.Verizon.en.US. It appears that the tun.ko module for kernel 
versions about 2.6.29 are somewhat finiky. I need one that will work with 
Kernel Version 2.6.32.9-g59f0395. I believe I have all the bugs worked out on 
ovpn connections minus this appropriate tun.ko module.

Could be a different format, I'm running this on an original Motorola Droid. If 
you folks could shoot me a copy of one one of the kernel modules that work on 
your phone (wifi driver or something) I could possibly be able to build one for 
you. If you are up for this e-mail it to me at

of course rename this module to tun.ko on your phone.

FYI,  I am trying out tun.ko referenced in comment 1 ( 
http://www.saturnwiki.net/droid_tun_driver/2.6.32.9/tun.ko ) with OpenVPN 
Installer / OpenenVPN settings from the marketplace.  That's OpenVPN 2.1.1 with 
OpenVpn Settings V 0.4.6.

Platform: Droid 1 FRG22D 2.6.32.9-g874c292

tun.ko from above appears to load, however there are other issues.  Reference

Thanks a million David!

That totally worked. I now got VPN to connect, now I'm faced with a new problem 
(doesn't actually pass traffic :(  ). I'll continue troubleshooting to see what 
I can dig up.

Thanks again,

I'm trying to get this working on a Droid2. I used the tun_alt.ko just to see 
if it would work and it did allow me to bring up the tunnel using VPNC. But 
like ramphalsa, it does not appear to be passing traffic. Ramphalsa, did you 
figure this out yet?
Thanks

I'm using your tun_alt.ko on my Droid 2 and I am having the same issue, I can't 
get traffic. Looks like an IP address from my server isn't getting to the 
phone. The configuration works fine on a Windows desktop, just not the phone.

I am not very familiar with linux VPN, so a lot of this discussion has been 
over my head. I installed VPN Connections, and downloaded the tun.ko file above 
and placed it inside /system/lib/modules. When I attempt to connect to VPN 
connections I get a FC.
I see a lot of the pieces around other forums, but nothing really listing the 
steps for people who aren't VPN or linux experts.
Do I need to change permissions on tun.ko file ?
I also saw some info about openVPN, but I am not sure about that either.
PLEASE help ??

Hi guys, sorry I took a little hiatus there. After I got it working, I 
completely forgot to update this thread (apologies to the support community)!

I've been using OPENVPN successfully on my droid2 for months now. The issue 
with the device not passing traffic turned out to be a problem with the OpenVPN 
Settings app (available on droid market). Once installed, I copied over needed 
certs and VPN config files and got the tunnel to connect, but noticed it wasnt 
passing traffic. 

The reason it wasn't passing traffic is because the path to ifconfig (need to 
set the tun adapter IP) and addroute (needed to create routes for the tunnel 
traffic) were hardcoded to incorrect paths in the app. You can create a 
symbolic link to get around this, although I believe (sorry for my failing 
memory, this was months ago) that I just copied ifconfig and addroute to the 
directory openvpn was looking for.

Hope that helps guys, thanks again to Rich S. for reaching out, otherwise, I 
would have never posted my fix.

Hi Ramphalsa, thanks for letting us know. I gave up on it after I couldn't get 
it to work, but your explanation does make sense.

Could you tell us where to put the symlinks at? I can't tell where openvpn 
settings is looking for ifconfig/addroute at. I know the binaries live in 
/system/bin.

Also, I don't have 'addroute' but I do have 'route'... I assume that is what 
you meant.

Thanks for the reply, and I hope to hear back from you soon with this last 
tidbit of info!

Hi Knight,

I unfortunately don't remember the paths. I do remember how I found them 
though. If you have terminal emulation on your droid (or you can connect it via 
USB cable and use the shell command line), you can run the openvpn by command 
and look at the verbose output on the command line (if any). I believe this is 
where I saw it calling /xbin/bb/ifconfig (or something to that effect) and it 
was failing because "ifconfig was not found."

I found it, without having to hook it up that way. I googled some more things 
and found a thread with relevant information about it here: 
http://code.google.com/p/android-openvpn-installer/issues/detail?id=2

Looks like it looks for the Busybox versions of route and ifconfig in the 
/system/xbin/bb directory no matter what, so, you have to create that 
directory, and create symlinks to /system/xbin/ifconfig and /system/xbin/route 
in that directory.

I did the above steps, using the kernel module linked in this thread, and now 
it works!!!

I just upgraded to a Droid2, and found that the last module I compiled would no 
longer work. So I had to recompile for this kernel, new driver is at

This attach file can not work on 2.3.3. Can you please compile a new one that 
work on 2.3.3? Thanks

Verizon might be causing problems on their side.  Interweb search for:

verizon wireless 3g NAT

or

verizon wireless 3g private ip address
