      Hi there,

      I'm a new pfSense user and currently trying to get my internet connection working in pfSense.

      I am in Australia on the Transact VDSL2 network (uses PPPOE connection). I configured my modem for bridged mode, have it connected to VLAN ID 2 (confirmed by my ISP) and in pfSense the WAN interface is connected and receiving a valid external IP address using my PPPOE credentials. My ISP can see my modem is connected however I'm unable to access the internet on my devices. I'm on the correct IP range, my pfSense LAN IP is the default gateway.

      I can't figure out what else to change in pfSense to let me access the internet. Any help for this n00b is greatly appreciated 👍

      Thanks in advance.

        @Dom293 What does pfsense show in the dashboard? Is the gateway showing UP?
        Can you ping IP's on the WAN side like the ISP gateway, or google (8.8.8.8)?

          @Gblenn yes, the WAN is showing UP and I managed to ping 8.8.8.8 without issue. I could see in the stats a small amount of traffic is going through the WAN and it has picked up the public IP etc. just was unable to hit a web page or anything at all.

          Some extra info, I'm on iiNet VDSL2, haven't been able to find anyone in the same situation in my searches. Also strangely when I reboot the pfSense box I can no longer access the webUI unless I fully reset the box and reconfigure it again, so not sure what's going on there either...very painful.

          So for now (night time) I've disconnected the pfSense box and reverted to my normal modem and connection and will do more troubleshooting tomorrow. But if you have any more thoughts, they are greatly appreciated and I can try out suggestions tomorrow.

            @Dom293 So if you are able to ping 8.8.8.8 but not able to "connect to internet", you probably have a DNS issue. Check your DNS settings in pfsense, and then on your PC and devices. I think default in pfsense is resolver mode which should work out of the box. Check what DNS your PC has ipconfig /all command will show you that info.

              @Gblenn Thanks for the feedback. I did a bit more tinkering this morning, checked a bunch of forum posts etc. But what I could see was the Gateway for IPV6 was blocking all traffic. So found a setting in 'System>Advanced>Networking' for 'Prefer IPV6 over IPV6. Checked that and everything started working. Not sure exactly why, but all good for now. I'll continue to monitor and tinker.

                Well if you choose Prefer IPv4 over IPv6 and that works now, i suspect you do have a invalid IPv6 Configuration. I suggest you shall fix that then, so you can use both, IPv4 and IPv6.

                In the OPNsense Manual you will find a chapter IPv6 for generic DSL dialup https://docs.opnsense.org/manual/how-tos/ipv6_dsl.html
                It exlpains how to setup the IPv6 configuration on a xDSL connection with PPPoE, similar as you have it. The Autor did test it with it's ISP Deutsche Telekom. I use it with my ISP o2 (Telefónica S.A.). Sure its out of the OPNsense Manual, but it its same on pfsense, just the names are slightly different.

                  @eagle61 agree, I planned on getting it sorted at some point so I've less thing to worry about. Might just be the monitoring IPV6 IP address for the gateway, wasn't sure what to set for that value. But thanks, I'll have a read through the doco over the weekend to try and get it sorted as long as it doesn't break my internet connection again 👍

                    If you talk about the monitoring IPV6 IP address for the gateway in System / Routing / Gateways its not the origin of your problems. This Monitor IP just shall answer on pings. That's all she did.

                    Go to Status / Interfaces section WAN Interface (wan, pppoe0). You will see there two Link Local-IPv6 addresses. named IPv6 Link Local and Gateway IPv6. The IPv6 Link Local works fine as Monitor IP.

                    But most likely that's not all what is to reconfigure at your IPv6 Config.

                      @eagle61 I don't think my ISP is setup for IPV6. I need to check with them, but that could be the reason it isn't working. Australian ISP are a bit behind the times.

                        If you check it out and the ISP supports IPv6, so check also what IPv6-prefix-size he will deliver. Here its mostly /56, but can be also /48, /60 or (in worst case) /64.

                          @eagle61 Thanks for the heads up, will definitely keep it in mind. Haven't managed to get IPv6 working yet, so strong chance it isn't support, but will keep checking.
