      you can not put same network on wan and lan..

      For ipv6 to work behind a router your isp should either give you a different /64 or a /128… Your lan /64 would be different than your wan..  just because you put /128 on the wan its still part of that larger /64

      And you don't put gateways on LAN interfaces..  its a LAN it doesn't have a gateway.. it is how devices on that network talk to other networks via pfsense.

      One way for a isp to hand you other networks to use on your lan would be thru prefix delegation..

        Thank you for the reply, will look for a larger block or another block at hetzner, otherwise i will try to get a booker account for the LAN

        PS: if i want to run a VPN/OpenVPN on pfSense box and assign ipv6 to clients do i need another block for that or can it be done with the same LAN IPv6 Block

        Regards

          another block..

          You know if your isp is not ready for ipv6 in primetime - just grab a tunnel from hurricane electric..  you can get a /48 from them with a couple of clicks for FREE!!

            Ok got a /48 and /64 block from HE

            added the /64 block to LAN

            everything works fine and VM's get LAN IP + IPv6 from HE

            Now just need  a way how to get OpenVPN working and to assign LAN IP and HE IPv6 to clients

            Thanks for the help

              this is pretty straight forward you should just have to put in the information in the openvpn setup.

              I ran into a slight issue, but turned out to be a hook for security software that was bound to my vpn interface that is not ready for ipv6 on the client once I remove that binding worked clickity clickity

              In the advanced section you can push route for ipv6 to go down the tunnel
              push "route-ipv6 2000::/3"

                  unless you want to do something special there is no reason to assign an interface to openvpn instances..

                      you would break the /48 up into multiple /64 you wouldn't use the whole thing ;)

                          what doesn't work ipv6 over openvpn?  You don't have a tunnel network..

                          Your not providing any dns servers to client.. What doesn't work?  Did you just run through the openvpn wizard?

                          Where are your wan firewall rules that allow the openvpn connection, this would be created auto if you ran the wizard.

                              "IPv4 or IPv6 addresses just when i did put in a ip it worked"

                              What IPv6 did they get?  You didn't put in a ipv6 tunnel network - so how is they would of gotten a ipv6 address???

                              Well without any dns how would you resolve anything?

                                i have tried to put in subnet, then removed it and all over again

                                Where do i put the DNS servers? should i use ISP or google DNS?

                                Thanks

                                  what do you mean where do you put in dns??  Right there on the openvpn setup screen..  Does googledns resolve your internal network devices?  Why would you not just point to pfsense..

                                    Hello,

                                    At this point I have no idea what am I doing or what am I doing right or wrong

                                    See the screen attached, i have added 8.8.8.8 and 8.8.4.4 under Client Settings > DNS Servers > I have ticked Client Settings and put the IP's there

                                    I can connect to OpenVPN server but there is no internet access i get IP 192.168.10.x and dns is googledns but rest fails hard

                                    Thanks again

                                          So this is where your doing it?  See pic

                                          On your CLIENT do an ipconfig /all.. what does it show for dns for the openvpn connection?

                                          So for example I connect to one of my vps running openvpn..  Now can you do a query via vpn, do a traceroute do you go down the tunnel to get to the dns you provided?
