Using my script, I can establish a working vpn for ipv4 and even able to ping ipv6 addresses.
However, trying to connect to an ipv6 address I get "permission denied".
➜ ping -6 ipv6.google.com -c1

➜ curl -6 ipv6.google.com

- Neither the server nor the client have selinux enabled.
- ipv4 works perfectly.
- ip forwarding for both ipv4 and ipv6 is enabled on both.
- masquerading is enabled on both.
I'm completely out of ideas.
