      After some help OpenVPN is connecting over IPv6 from the OpenVPN client on Android. I can use Termux on Android to ping hosts on the LAN by IPv4 address but I cannot load web pages in the browser on the client - even using just the server IPv4 address in the browser. What is going wrong?

      Here some details:
      LAN subnet - 192.168.88.0/24 gateway 192.168.88.1
      VPN subnet - 192.168.77.0/24 gateway 192.168.77.1

      Interfaces - all up in the dashboard:
      WAN - 100.77.0.23 and IPv6 2a00:6020:1000:1d:abc:beef
      LAN - 192.168.88.1 and IPv6 2a00:6020:1920:c01d:c01a:1324:beef:babe
      OVPN_IF - 192.168.77.1 and IPv6 2a00:6020:1000:1d::1

      Firewall rules - the logs look clean

      I think these rules are too permissive from my half-understanding of things I have read but would fix this after getting things working.

      My guess here is that maybe the IPv6 Tunnel Network I set in the OpenVPN server is wrong - I just guessed based on the WAN IPv6 address (see interfaces above) and used 2a00:6020:1000:1d::/64 but why ping would work and web pages not doesn't seem consistent. Otherwise perhaps there is some weird option set somwehere.

      Any help gratefully received.

        Any suggestions anyone? I am completely out of ideas and my hacking at the settings is likely now just making it worse...

          Looked for it, but couldn't find one.

          Just an idea : make everything work with IPv4 first.

          Use something like this :

          cde04d89-d3fb-4d36-a171-915fa3ee0839-image.png

          as I guess you use the VPN - and you're the admin anyway, so why block yourself ?

          No "help me" PM's please. Use the forum, the community will thank you.
          Edit : and where are the logs ??

            Thanks - they really should make the "Remove final obstacle" check-box easier to find 😰

            Regarding the IPv4 idea I have been lead to believe from a previous question that my provider only gives me the possibility to connect over IPv6 - which doesn't seem to be an issue as OpenVPN does connect and internet pages load in the browser. It it just web pages hosted by servers on my LAN which don't.

              Still no idea... I even rebooted pfSense to no avail. I did notice that even when the client shows 'initialisation sequence complete' pfSense OpenVPN status shows no client connected. There is obviously something wrong.

              A couple of specific questions -

              • I gave my OpenVPN server an IPv6 Tunnel Network of 2a00:6020:1000:1d::/64 which is a complete guess. I have no idea if this is going to work. Can anyone help me be sure this is OK?

              • On the Dashboard the OpenVPN Gateway is always Offline - I have verified the IPv6 address it is pinging (2001:4860:4860::8888)can be reached from pfSense ping diagnostic so could this indicate a problem?

              • I read that adding the Advanced Configuration option push "route-ipv6 2000::/3"; is required in the OpenVPN server options for IPv6 connections. Is this true?

                I've been asking myself the same qestion.
                That's why I defalted to a known good RFC 1918 IP network like 192.168.3.0/24.
                After all : the Internet gods will come after you if "2a00:6020:1000:1d::/64" is assigned to some one ;))

                That's not a good sign.

                20ea0991-ff85-4d44-a0a6-03dd94d45e3a-image.png

                As I'm using 192.168.3.0/24 and 2001:470:xxxx:3::/64 - I own both of them, as 192.168.3.0/24 is RFC1918 and 2001:470:xxxx:3::/64 is part of an IPv6 network that I'm allowed to use.

                The tunnel goes over IPv4 (I guess / I don't care ^^).

                What about the more official doc ?

                  Many thanks - the official document you gave me is a bit more informative (and less German ☺).

                  I have been reading docs on IPv6 addressing and am not sure what what IPv6 Tunnel Network I should use. My service provider uses DHCPv6 and a DHCPv6 Prefix Delegation size of 56 in the WAN interface. In the dashboard WAN shows a WAN IPv6 2a00:6020:1000:1d::bbc:beef. I am assuming that as I get a /56 from my provider I should choose a /64 for OpenVPN like the docs say - but what is the correct /64 I should use?

                  I did notice that even when the client shows 'initialisation sequence complete' pfSense OpenVPN status shows no client connected. There is obviously something wrong.

                      So that looks like just a NAT problem?
                      And for the tunnel you still could use IPv4, even if the tunnel is running over IPv6 I guess.

                        It could be - previously in my OpenVPN configs the automatic NAT just worked so I am a bit confused what settings I should use. I read around a bit and ended up with what is below - but the automatic outbound NAT gives the same behaviour.

                        Can you help me get this working?

                          Another week later and I am still going round in circles - can anyone help me debug this? It is curious that even when the client is connected the client does not show up in OpenVPN -> Clients and the OpenVPN gateway is offline on the Dashboard. I am wondering if there are deeper problems and the connection is somehow broken - but I have never seen anything like this before and do not know how to debug.

                          Perhaps there is something fishy in the client log:

                              Many thanks for the suggestion - I tried that, exported a new client profile, and unfortunately no difference.
