Hello Paul, ...

As one option, it is possible to spin up a systemd-nspawn container, run
the openvpn server in there with it's own networking namespace, and map the
port of the openvpn server to the host.
You can make all kind's of scenarios, ...

Greetings, ...
Dear systemd folks,
Our users sometimes need to access the internal network of another
organization, but unfortunately SSH access is blocked, and it’s only
over OpenVPN. With that, they could use their browser and SSH to access the
internal network.
Due to security reasons, we do not want to allow OpenVPN on our systems,
wonder, if systemd user service would enable us to run OpenVPN
unprivileged for
a user, so that the user has no chance of disturbing other users.
OpenVPN provides systemd units [1].
Do you think, it’d be easily possible, that the OpenVPN sets up the
in a separate network name space, and the user can enter that name space
start SSH and a browser from there?
If yes, do you have any hints before I start to dig into that?
Kind regards,

opening TUN/TAP interfaces and changing routing is a privileged operation.
