      Yeah, it should work with netgraph because there are no restrictions really. You can do whatever you want there unlike ifconfig.

      It shouldn't be that hard either. Another think that uses it is QinQ. If you create a QinQ interface and then check in /tmp you can see the file with the netgraph commands used to create it.

      Or indeed the example given here.

        Running packet capture on the WAN port all I see is a DHCP discovery broadcast (by my unit) and a DHCP offer by provider which unit never responds to but causes it to put another Discover out there.

        Offers are tagged:

          A GS105NA can be had for around $45 on amazon.ca.

            If you didn't have to priority tag it on the USG you wonl't have to here.

            This is going to be like a 5 line script but Netgraph always makes my brain hurt!
            Just hitting errors right now....

              @stephenw10 the only setting i set on the Unifi USG3 was "Use VLAN ID" and I set it to "0"

              I was able to do a temp work around with a 24 port Cisco Small Business switch that I had and put it between ONT and pfSense. This allowed me to grab a DHCP address from provider and surf. Overkill solution.

              Will continue to look at the netgraph option... as this seems like the cleanest option. I just need to wrap my head around how netgraph work and how to compile as I dont have a system running FreeBSD (outside of this pfSense box).

                  Just to point out - unifi doesn't make this as easy as made out to be..

                  unifi.png

                  They might support it on some versions of the controller software in some places - but like most applications 0 and 4095 are not really valid

                  Is there a feature request for this? If there are ISPs that want/need this - and freebsd allows for it, etc. I would expect if there was a feature request for it - it would/could be looked at implementing in the gui as a check box, or something.

                  But in 30 some years in the biz - sorry but setting vlan 0 is not a common thing.

                    @johnpoz having this as an option would be amazing. Would be simple than some of the other work arounds.

                    Hard to believe others haven’t asked for it based on ATT also needing it (amongst other config). Not used what other ISPs are similarly config’ed.

                      I haven't combed through redmine yet - but yeah if you want/need this - then it should be submitted to redmine as a feature request..

                      If it can be done, and there is desire for it - why would it not be implemented.

                      But to be honest - I do believe part of the reason for such a deployment would be making it harder for isp customers to use non isp hardware.. Since setting vlan id 0 is not really something that is common

                        @johnpoz I configured in the initial USG config. Not using the controller software.

                          @johnpoz sorry, I am not sure who/ what Redmine is. This is my first post and I just got pfSense installed this week. I am very new to since. My initial excitement did fizzle somewhat when I ran into this issue.

                            Question:

                            Why not run it in transparent mode and let pfsense handle WAN??

                              @cool_corona not sure I understand what you mean. New to pfSense can you elaborate?

                                @natbart You put the Nokia in bridge mode and connect the pfsense WAN on RJ45.

                                Then handle WAN via DHCP to see if it works. And then you are rid of the USG

                                  As I understand it that is the plan here. But the ISP requires the traffic tagged as VLAN0 and pfSense does not currently have any way to set that.

                                  Netgraph still defeating me!

                                      thanks for the tip. As far as I know I have no access to the Nokia ONT. It is doing media conversion from Fiber to Ethernet and is otherwise a black box to the end-user.

                                        @stephenw10 I appreciate any work you are attempting to do with Netgraph! I havent been able to dig into it any more myself.

                                          If you look at the att netgraph scripts, they could be useful in solving the vlan0 issue. They handle that, but have a lot of other functions not needed in your case. You should be able to start with them and pare it down to pretty much nothing if you don't need the gateway auth bypass etc...

                                            I did start looking into that, but there are more differences than similarities. It got me looking at Netgraph, but that is requiring some more learning. @stephenw10 was also graciously looking into netgraph.
