I’m creating a server with OpenVPN to mask my IP address using this [article](https://www.digitalocean.com/community/tutorials/how-to-set-up-and-configure-an-openvpn-server-on -ubuntu-20-04-en) from DigitalOcean.
The setup worked perfectly when I configure Redirect All Traffic Through the VPN, all my accesses on sites with IPv4 display the Droplet’s IP.
The problem occurs when I access sites that accept IPv6, in these cases the displayed address is that of my ISP.
Below the line
net.ipv4.ip_forward = 1
I added the value
net.ipv6.conf.all.forwarding = 1
but nothing happened.
How do I also enable the use of the Droplet’s IPv6?
