Common questions about IPv6 Support for OpenVPN Access Server
- Can Access Server accept incoming IPv6 tunnels?
No. OpenVPN Access Server is primarily an IPv4 system and requires an IPv4 address for its OpenVPN daemons to process incoming connections. The tunnels themselves can transport IPv6 packets.
FYI: The information inside the tunnel itself is the payload layer or tunnel layer, and the encrypted packets that the OpenVPN daemon transports between VPN client and VPN server are the transport layer.
- Can Access Server transport IPv6 in the VPN tunnel?
Yes. Access Server version 2.0 and newer support IPv6 at the tunnel layer, but not the transport layer. For more information refer to this Document
