      Recently moved from a cable modem with an IPv6 tunnel setup (he.net) that was working to AT&T fiber and now the tunnel stopped working. I've put the fiber modem (BGW320) into passthrough mode, disabled the IPv6 and it's firewall.

      Using an SG2100 and it was working just fine on the cable modem to SparkLight. I've poked around in the pfSense and I don't see anything that seems to be set differently now. Is there something about this fiber modem that will block a tunnel from working? Searching the webs I do find that protocol 41 could be the cause but I'm unsure if AT&T blocks that protocol.

        @BiloxiGeek You have to update your IPv4 with HE.

          Doesn't AT&T provide native IPv6? I only used a tunnel until my ISP provided it native.

          PfSense running on Qotom mini PC
          i5 CPU, 4 GB memory, 32 GB SSD & 4 Intel Gb Ethernet ports.
          UniFi AC-Lite access point

          I haven't lost my mind. It's around here...somewhere...

            @Bob.Dig I update my IPv4 through a DynDNS setup so tunnelbroker knows about my new IPv4 address.

              @JKnott I'm gonna look into that but I was wanting to just keep the setup I already have but using the AT&T fiber connection which is faster especially on the upload side.

                @BiloxiGeek And it has to be ping-able.

                  @BiloxiGeek and they give you a public IP, or is cgnat? For you to create a tunnel, you have to be able to ping the IP..

                  You are using this setup for your IP change?

                  I know its quite dated.. And I have not had to change mine in years and years - I just have the actual IP in my tunnel setup on HE.. If my IP changes I would just update it on HE..
