network-manager-fortisslvpn not working but openfortivpn does

[robin]

I've used network-manager-fortisslvpn to establish a VPN but it doesn't work. I setup the VPN and then try to load a web page which can only be loaded if on the VPN. The window keeps still trying to connect (dots indicating loading keep moving)
I do it directly from a terminal, via openfortivpn, i.e. I run the command
openfortivpn the.apropriate.url:port -u my.user
and it establishes the tunnel OK. I'm able to load the said page right away.

This is a critical bug with network-manager-fortisslvpn incompatibility with openfortivpn >= 1.11.0. This package is useless right now. Ubuntu needs to repackage it with a patch.

Before openfortipvn 1.11.0 the default configuration was equivalent to:
--set-dns=1 --pppd-use-peerdns=1
Starting with openfortivpn 1.11.0 the default configuration is equivalent to:
--set-dns=1 --pppd-use-peerdns=0
NetworkManager-fortisslvpn expects the configuration to be equivalent to:
--set-dns=0 --pppd-use-peerdns=1
This expectation breaks with openfortivpn 1.11.0 because NetworkManager-fortisslvpn only passes this command line option:
--no-dns / --set-dns=0
Starting with openfortivpn 1.11.0 it needs to be:
--no-dns / --set-dns=0 --pppd-use-peerdns=1

There is already a patch. More information on: https://gitlab.gnome.org/GNOME/NetworkManager-fortisslvpn/-/merge_requests/13

There is a patch on Fedora's package: https://src.fedoraproject.org/rpms/NetworkManager-fortisslvpn/c/6378487

Hi, 3 years down the road, any update on this? NetworkManager-fortisslvpn is now available as 1.4.0 (a .deb exists in Debian 12/unstable), but Ubuntu is still stuck with 1.2.10. Thanks.
