YES with this patched vpnc you can connect from a rooted desire (or any other android device) to your AVM fritzbox with the original firmware. The included vpnc-script will help to fix the routing problems.

You need a rooted Android device with an tun.ko module

First setup your fritzbox like the iphone setup which is described at the avm portal (google-> "avm iphone vpn")

Install signed-FritzBox.apk to your phone.

Setup now your vpnc-gui and be happy.

--------------------------------------------------------------------------

Some detailed infos how to connect the Fritzbox with IPSEC via VPNC:

1.) you must use a IKE_ATTRIB_LIFE_DURATION = 3600 (seconds)
2.) you must use draft-ietf-ipsec-nat-t-ike-03

the original vpnc uses a IKE_ATTRIB_LIFE_DURATION with 2147483 (seconds) and only uses draft-ietf-ipsec-nat-t-ike-00 -> 02.

I change the timing to 3600 (seconds) and change the transformset 02 to 03.

Timing -> find in vpnc 000020C49B and change it to 0000000E10 (2x)
Transformset -> find in vpnc CD60464335DF21F87CFDB2FC68B6A448 and change it to 7D9419A65310CA6F2C179D9215529D56 (1x)

By the way these patch will help any vpnc user on every linux (i tested this with ubuntu and it works perfect)

----------------------------------------------------------------------------
update 20.12.2010

----------------------------------------------------------------------------
New APK to install on a rooted Android device. After installing you can connet via IPSEC VPN to a cisco device and to the FritzBox with the latest Firmware without modifying the FritzBox


For all who wants to use the FritzPhone App to make phonecalls via vpnc this will not work because the app did not use the 3G interface (only wlan). Download the app "3cx" from the market and in the setup menu "integration" you will find "Enable 3G", thats all.

Hi there!

Really nice one but I'm getting a forced closed when I push the connect button.

I'm using a SE X10 with android 2.1.........

Sometimes I hate my phone.......

Merry Christmas.

Is your Device rooted and had the vpnc the exec permissions ?

Please install "Quick System Info" and check the loginfos via the Logcat.

Maybe in your Kernel the tun.ko is missing.

Hello

@mp1405

Thanks for the signed-FritzBox.apk. I finally got it running on my Samsung I9000 Froyo XXJPU and Fritzbox 7390

First I had also the FC because the tun.ko was missing. Now it works but but I have to load the kernel module every reboot in the konsole with insmod /system/lib/modules/tun.ko

I edited the file /init.rc with the line insmod /system/lib/modules/tun.ko but every reboot a "recovery" init.rc is loaded without my insmod line. There was also the tip to copy the tun.ko into /lib/modules/tun.ko but the tun.ko gets deleted after every reboot.

Kind regards

Thanks for your work and time for this patched Version.

For my understanding:
IPSec ID is what ? My e-Mailadress from the FritzboxConfig ?
IPSec Secret is the Passphrase ?
Is this correct ?

Thanks!

Hello

IPSec ID: Yes, your e-Mailadress from the FritzboxConfig (it is the entry "user_fqdn" which you have to replace with "key_id" in the config.

IPSec Secret: Is the Passphrase (also named Pre-Shared Key or just "key") in the Fritzbox Configs.
