OpenVPN Support Forum

I love Openvpn and have been using it for every testing pod I build, ipv4 only tun and mixed ipv4 and ipv6 tun. Looks like I have ran into a small issue. I need to only use IPv6 for tun and server addresses. This small testing pod can only can have IPv6 addresses within it. Is this even possible on under Ubuntu LTS 16.04?

Currently, OpenVPN requires that you have IPv4 configured inside the tunnel, which you can add IPv6 to as dual stack. What you do outside the tunnel is up to you.

Thank you for the reply.

Would you know if this is documented on OpenVPN's site? I need to show my management some type of official documentation stating all OpenVPN requires an internal IPv4 tunnel.

See IPv6 at the openvpn wiki.
