<![CDATA[pfSense IPv4+IPv6 & OpenVPN]]>for years I worked with a server openvpn + ipv4 it worked great, today I decided to add ipv6 to the tunnel (but when I go to test-ipv6 .com) to test it says ipv6 not detected does anyone know why?

The 'correct' settings here are very much dependent on what your ISP provides.

What exactly is not working here?

Above you showed the interfaces widget with the valid public IPv6 address. Are you still seeing that?
Do you have a default route for IPv6?
A link-local gateway like the can be valid if the ISP is passing you a prefix and routing it to you.

And you are able to connect to it from a Windows client but it only gets an IPv4 IP address? Or gets an IPv6 address but cannot connect out?

It looks like pfSense itself is getting an IPv6 address via DHCPv6 but cannot ping out.
You have set the source address as WAN link-local which is usually not routable. Does the ping work if you set the source to WAN or automatic?

Obviously your browser cannot do any IPv6 request.
Maybe the computer has no IPv6 or you have no IPv6 WAN address or you have disabled IPv6 on pfSense or there is no rule on LAN which allows it.
But whatever the reason is, it doesn't necessarily have anything to do with the OpenVPN server.
