Hello, I know there are many examples out there but I have this post (in spanish) about to have IPv4 and IPv6 in one VPN using OpenVPN: https://blog.acostasite.com/2018/05/ipv4-e-ipv6-en-una-sola-vpn-utilizando.h... Alejandro, El 11/3/19 a las 06:33, Gert Doering escribió:

I am checking which VPN solutions are IPv6 compatible outside and inside the tunnel and can so transport with any IPv6/IPv4 connection IPv6/IPv4 internal to then tunnel [..] OpenVPN https://community.openvpn.net/openvpn/wiki/IPv6 No complete example found yet. OpenVPN can do what you're asking for.
The wiki page is old and needs work. The config options described are correct ("--server-ipv6", "--ifconfig-ipv6", "--route-ipv6"), but the part about "you need to do 'proto udp6'" is 2.3.x style (which can use either IPv4 or IPv6 outside the tunnel, but not auto-detect what is needed), while 2.4.x is fully dual-stacked and will use whatever is in DNS and/or in the config.
