android ipv6-only openvpn connect problem

[cberni]

My server Client-to-Site is running on Ubuntu 20.04 lst server with OpenVPN 2.5.0.
I don't need internet through vpn. Only to connect to ours server.

The connection is proto udp ipv4 but inside the tunnel is ipv6-only.

O my iPhone (Apple) with openvpn connect 3.2.2 (3507) all works fine. Tunnel and internet.

But on any android (openvpn connect 3.2.4 (5891)) when connected to the vpn the internet stop working. Only connection with ipv6 tunnel works and no internet.

If I add ipv4 inside the tunnel. The internet and tunnel works fine on android.

Seens that all traffic is trying to be over ipv6 tunnel when ipv6-only is seted on server.

Is there any config I should do to get ipv6-only working on android? And internet data passing normally outside the tunnel?

I guess your Android needs IPv4 ?

Hello Guys, I'm having trouble with OpenVPN Connect on Android when using an IPv6-only network. The connection either fails to establish or drops quickly. Has anyone found a reliable solution or workaround for this issue?nulls brawl
