Since 2.3.0, OpenVPN officially supports IPv6, and all widely used
|
|
patches floating around for older versions have been integrated.
|
|
|
|
IPv6 payload support
|
|
--------------------
|
|
|
|
This is for "IPv6 inside OpenVPN", with server-pushed IPv6 configuration
|
|
on the client, and support for IPv6 configuration on the tun/tap interface
|
|
from within the openvpn config.
|
|
|
|
The code in 2.3.0 supersedes the IPv6 payload patches from Gert Doering,
|
|
formerly located at http://www.greenie.net/ipv6/openvpn.html
|
|
|
|
|
|
The following options have been added to handle IPv6 configuration,
|
|
analogous to their IPv4 counterparts (--server <-> --server-ipv6, etc.)
|
|
|
|
- server-ipv6
|
|
- ifconfig-ipv6
|
|
- ifconfig-ipv6-pool
|
|
- ifconfig-ipv6-push
|
|
- route-ipv6
|
|
- iroute-ipv6
|
|
|
|
see "man openvpn" for details how they are used.
|
|
|
|
|
|
|
|
IPv6 transport support
|
|
----------------------
|
|
|
|
This is to enable OpenVPN peers or client/servers to talk to each other
|
|
over an IPv6 network ("OpenVPN over IPv6").
|
|
|
|
The code in 2.3.0 supersedes the IPv6 transport patches from JuanJo Ciarlante,
|
|
formerly located at http://github.com/jjo/openvpn-ipv6
|
|
|
|
OpenVPN 2.4.0 includes a big overhaul of the IPv6 transport patches
|
|
originally implemented for the Android client (ics-openvpn)
|
|
|
|
IPv4/IPv6 transport is automatically is selected when resolving addresses.
|
|
Use a 6 or 4 suffix to force IPv6/IPv4:
|
|
|
|
--proto udp6
|
|
--proto tcp4
|
|
--proto tcp6-client
|
|
--proto tcp4-server
|
|
--proto tcp6 --client / --proto tcp6 --server
|
|
|
|
On systems that allow IPv4 connections on IPv6 sockets
|
|
(all systems supporting IPV6_V6ONLY setsockopt), an OpenVPN server can
|
|
handle IPv4 connections on the IPv6 socket as well, making it a true
|
|
dual-stacked server. Use bind ipv6only to disable this behaviour.
|
|
|
|
On other systems, as of 2.3.0, you need to run separate server instances
|
|
for IPv4 and IPv6.
