Dear Sailors,

I am trying to connect my Jolla1 to my Fritz!Box 7490, but something is not going well. I have managed to connect my laptop running Ubuntu Linux 18.04, so I have tweaked around with the settings according to that, but it doesn't work.

Has anybody managed to get this running?

Thanks a lot!

Cheers Dejan

Jolla deploys vpnc without the "recent" patches needed for VPN with the AVM Fritzbox. The version number is the most recent, but there is a "new"(2014) build of vpnc binary from a maemo thread via previous discussion.

For testing I replaced (after a backup) /usr/sbin/vpnc with the above binary and the VPN-GUI seems to work. The Fritzbox immediately shows the status of the relevant user as "active" in -> Internet -> Freigaben -> VPN .

@gust: could you tell me what you did to make it working? you configured the connection via the sailfish GUI or the "/etc/vpnc/default.conf" file? any test I did returns always a connection error.

Can somebody tell me, if the changes in the vpnc package ( in the 3.0.2 update contain the patches needed or do you still need to load the alternative version from the thread?

Update: Seems like Jolla added IPSec support via the VPNC package, so you are correct that it should work. For a long time, SFOS only supported OpenVPN, hence my assumptions on the original post. Sorry to miss the update.

So, what are the errors you are getting when the connection fails?

Original post (outdated):

Based on your title and a quick research, I'm pretty sure that the FritzBox VPN bases on IPSec, while the VPN implementation in SFOS is based on OpenVPN. These two protocols are completely different and not inter-operable, so your only possible options are:

  • get IPSec support on your Jolla (most likely with strongswan): As far as I know, there is no easy way for that (no App or GUI), you'd have to compile the package itself and manage everything from the command line
  • switch the VPN on FritzBox to OpenVPN: This seems not possible, since FritzBox does not have OpenVPN support in its Firmware (and most likely will not add it).

So unless you have some knowledge in compiling and shell management and are willing to experiment with it, there's no way in connection your Jolla to a FritzBox. Nevertheless, feel free to contact the Jolla Support ( to confirm my assumptions (and show them, that there is a demand for IPSec support).

One thing you could do of course is running an OpenVPN server behind your FritzBox, if that is an option for you.

Well, when I open up new VPN settings, the third textbox on the first screen is called IPSec identifyer. No you tell me, that SFOS does not support IPSec. How does that fit with your answer?

VPN on Jolla is still beta, and OpenVPN is the only option usable. So far.

Copy that. :-)

@ds1979 : sorry, you are correct. I missed the update where Jolla added IPSec support via VPNC. I've updated my answer.

Well, my phone is working on german, so it states: "Problem mit der Verbindung - Automatisch wiederverbinden" which would be in english: "problem with the connection - automatic reconnection"

I don't know how to read the log, so some help would be handy. Perhaps I will find some hints to fix that.

By replacing the vpnc binary, I could use the GUI to connect, but the connection did not actually route any packets. Even after adding a route, it did not work. Setting up a /etc/vpnc/default.conf, starting from the cli and then adding a route, did work, though. So the guide at the bottom of is still valid.

(On Sailfish X with today's update to rev. 3.)

For me replacing the vpnc binary worked well. Thanks a lot ! Fritz!Box7560
