Nov 14, 2019 · Virtual private network technology is based on the concept of tunneling.Just like a water pipe contains the liquid flowing inside of it, a VPN tunnel insulates and encapsulates internet traffic—usually with some type of encryption—to create a private tunnel of data as it flows inside an unsecured network.

I tried to configure the server, such that my IPv4 internet traffic is routed through the tunnel. The problem is, during connection to the VPN server is established, IPv4 websites are not loading at all. Furthermore IPv6 traffic still slips through, such that IPv6 websites load as usual. The IPv6 availability on the tunnel interface depends on it being provided by your commercial VPN. There is also a very good reason for not using IPv6 when running a commercial VPN: if the goal is to hide your identity, but you give each client a unique public/global address (IPv6), even if just for their current browsing session, then it I have searched several tutorials but many of them are vague, incomplete, or do not give enough help to actually configure openvpn for ipv6 connectivity. My goal is to be able to connect to both ipv4 and ipv6 services/websites. Jul 26, 2017 · You can choose not to tunnel IPv4 and IPv6 traffic so that only local traffic goes through the VPN. That’s useful if only need to use the VPN to access remote resources not available from your normal internet connection, but not much else. Furthermore, Windows only split tunnels VPN protocols that it has built-in support for.

I'm running OpenVPN server on company's linux host named ubunku (Ubuntu 18.04.4 LTS). My company's gateway (router) has both fixed IPv4 global address and native IPv6. And there is IPv6 support on my home. So I want to use IPv6 for OpenVPN connection. It is ok: home(IPv4) to company(IPv4) OpenVPN Server It is not good, having error:

Nevertheless, I am able to take IPv6 on the road with me by creating a 6to4 tunnel through the OpenVPN IPv6 tunnel. In this configuration, the IPv4 address pair (172.20.0.10,172.20.0.11) is used for the OpenVPN tunnel and (2001:470:e857:2::1,2001:470:e857:2::2) is used for the 6to4 tunnel. Here are my config files:

We now tunnel IPv6 as well as IPv4. This means you can get connected to the IPv6 internet through Mullvad, even without IPv6 support from your internet service provider. It is not yet enabled by default as it does not work on some Windows computers. To use it, get the latest client program. Go to Settings and enable Tunnel IPv6. Try to reconnect.
