Jul 20, 2008 · I was searching for VPN default behavior with IPv6 and found this. So, if your VPN gateway is IPv4-only, and your security policy is no-split-tunnel, but the VPN client is plugged in at home where somebody has dual-stack. . . suddenly the client is running split tunnel? Cisco AnyConnect doesn't have this vulnerability by default.

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: What I'm trying to do is to route IPv6 traffic through a vpn tunnel. That way, I should be able to use IPv6 in a network that doesn't support IPv6. I have a VPS which has an IPv6 block assigned. Part of this block I want to use for openvpn clients. Jan 23, 2019 · IPVanish (No IPv6 Support) IPVanish doesn’t support IPv6, and their public documentation says that IPv6 connections may be routed outside the VPN tunnel. The IPVanish software does currently have optional IPv6 leak protection or you can manually disable IPv6 on your router to be safe. - 2001:412:abcd::/48 - Local IPv6 network - 192.168.2.0/24 - Tunnel IPv4 network - 2001:412:abcd:2::/64 - Tunnel IPv6 network. I have included only the sections of config files which need ammending to enable IPv6 over OpenVPN. Client Config # Use the same setting as you are using on # the server. # On most systems, the VPN will not function Feb 28, 2017 · IPv6 traffic is effectively rerouted to a “black hole” within the device. This feature happens by default on all NordVPN applications that use OpenVPN, requiring no user action. IKEv2/IPsec protocol does this automatically. Up next, we plan to tackle the IPv6 support on our servers – follow our blog for updates on the topic.

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.

Trying to learn how IPv6 works with OpenVPN, so I wanted to setup following scheme. I have a VPS server (Ubuntu), which have been allocated a /48 subnet. ISP ipv6 gateway is XXXX:XXXX:XXXX::1 Server ipv6 address is XXXX:XXXX:XXXX:39::1 The idea is that any clients connecting to server gets an ip address on the XXXX:XXXX:XXXX:39:2::/64 subnet. So until IPv6 split tunneling rules are available via the ASA, the client will not support arbitrary leaking of IPv6 data outside of the tunnel. This is true even if ipv6 is not configured for anyconnect. So to sum up, the AnyConnect client does not support split-tunneling of the IPv6 traffic. All IPv6 traffic must go over the AnyConnect tunnel You will see the IPv6 address in the Current IPv6 Address Table. Then, specify the IP address of IPv6 Gateway. 6in4 Static Tunnel. In this mode, the IPv6 connectivity is provided by a tunnel broker on the IPv4 Internet through a tunnel configured manually. To use the 6in4 Static Tunnel, you need to sign up for a tunnel broker service. When connected to an address that only supports IPv4, they will serve up an IPv4 address, but when connected from an address that supports IPv6, they will serve up an IPv6 address. Unfortunately, most VPN software fails to direct IPv6 traffic through the VPN tunnel, so when you connect to an IPv6 enabled website, your browser will make an IPv6

in order to make the VPN server available over both IPv4 and IPv6, and to add the following lines: server-ipv6 2600:3c01:xxxx:xxxx::/64 push "route-ipv6 2000::/3" to bind to the right V6 address and to tell clients to tunnel all V6 Internet traffic through the VPN.

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.
