Openfortivpn malfunctions with KDE Network Manager

[msdobrescu]

Openfortivpn seems to connect, to create the routes, to add the DNS servers, but it can't access the services behind, there is no ping response, although the commercial version under Windows works for the same connection. Compared to the Windows version, it seems to generate the same setup. Also, it stays for some time connected, maybe 10-20 mins, then disconnects.

My system is a Gentoo-based distro, MocaccinoOS, we use openfortivpn 1.20.3.
I've tested under KDE Plasma, where the Network Manager integration seems to be the cause, as the CLI version works fine. Although seems similar to #1120, version 1.20.3 does not work for me either.

The OpenVPN client and works fine with the KDE Network Manager.

Please open a ticket against KDE Network Manager. It's probably (although never certainly) KDE Network Manager malfunctioning with openfortivpn, not the other way round.

The report is here: https://bugs.kde.org/show_bug.cgi?id=472491
They've read your devs comments and decided is not their issue!
Tried under Gnome, there Network Manager does not claim it connects, it simply goes back to disconnected instantly.

I understand openfortivpn works for you from the command line, doesn't it? If so, how isn't this an issue with the GUI integration?

[msdobrescu]

Well, this is what I try to figure out, actually.
As you can see, KDE team denied it's their fault, so I'd appreciate if you reply to them on the matter, as you may know better how to prove it's their issue, as I incline too.

In my experience, KDE and Gnome integrations are suddenly broken, but I am a KDE user, Gnome being just a "witness".
Also, openvpn interations work in both DEs.
Maybe they've missed something when changed the implementations, although I wonder why would change this ignoring openfortivpn particular parametrization?

It's much more likely that the issue is with NetworkManager(-fortisslvpn), not Plasma's UI for it.
