[Pkg-utopia-maintainers] Bug#1014913: network-manager: Follow Up: L2TP-VPN still doesn't work (worked with 1.34.0-1)

[Marcel Jira]

Package: network-manager
Version: 1.38.2-1
Severity: important
X-Debbugs-Cc: marcel.jira at gmail.com

Dear Maintainer,

In March 2022 I reported bug #1007899 (https://bugs.debian.org/cgi-
bin/bugreport.cgi?bug=1007899) that prevents me to connect to a L2TP-VPN. Until
version 1.34.0-1 the connection was working.

The problem still couldn't be solved even after updating to

* network-manager 1.38.2-1
* network-manager-l2tp 1.20.2-1
* network-manager-l2tp-gnome 1.20.2-1

Also, me and our IT department were able to reproduce this bug with a fresh
installation of Debian Bookworm, Ubuntu 22.04 and Ubuntu 22.10.

The L2TP VPN is provided by a hardware firewall ZYXEL USG60.

I shall be happy to provide additional information in order to get this problem
resolved.
