openvpn3 connection changes IP v4 address but not IP v6 address

[flagellatedcucumber]

Currently using openvpn3 version:
OpenVPN3/Linux v20 (openvpn3)
OpenVPN core v3.7.2 linux x86_64 64-bit
Copyright (C) 2012-2022 OpenVPN Inc. All rights reserved.

This is the package available via this Linux's distro's repository, version is listed as "20+jammy". This is the system package, not a flathub package.

I can successfully connect to a vpn connection and I see the IP v4 address change. But the IP v6 does not change: the IP v6 address remains the same before, during and after the VPN connection.

Why is this? What diagonsis is needed, if any?

First I would ensure you're on a recent release, v20's over 2 years old. v26 is the latest version:

And second I would check if your server is actually handing out IPv6 addresses. Commonly it only hands out IPv4.

I'm surprised this package came from the "system repo". I would not have expected that to be backported from Ubuntu 25.04 (where v24.1 is the only version available). So I presume you have a potentially outdated repository file in your system.

Please check that your repository for OpenVPN 3 Linux is correct ... https://community.openvpn.net/Pages/OpenVPN3Linux

I'm also closing this issue - as this is the wrong place for OpenVPN 3 Linux related issues. Please open a new issue on Codeberg: https://codeberg.org/OpenVPN/openvpn3-linux/issues/
