I have a virtual server with an ipv4 public ip address and a pool of ipv6 public ip addresses assigned to the various interfaces eth0: 2, eth0: 3. The interfaces are fully functional and there are clients like znc clients that exploit them. I have created a traditional openvpn server that routes all client traffic to the ipv4 address. However, I would like traffic to a specific ipv6 to be assigned and routed to every open vpn client file. How can I do?
