While ipv6 is becoming more common, not many ISP’s do provide ipv6 addresses to their customers. But what if you have some ipv6 /64 subnets, e.g. on a hosted server, and you want to provide ipv6 access to locations that only have ipv4? Simply become your own ipv6 provider, using OpenVPN!
In this post, we explain how openvpn can be used to add ipv6 access to clients that only have an ipv4 connection to internet. The next post extends this example to routing ipv6 subnets through openvpn, allowing every machine in the office network behind the openvpn client to have ipv6 access.
To provide openvpn clients with ipv6, you need a server that has both an ipv4 address and some unused ipv6 /64 subnets. The OpenVPN server will be accessible through ipv4, and an ipv6 /64 subnet can be routed through the OpenVPN Tunnel.
