      Setup:
      To link archer vr600 modem router in bridge mode
      Provider requires vlan tag 101 and mtu 1480
      Provider doesn't care what router/Mac address I use

      Pfsense plugged to Lan port 1 of vr600(tried them all)

      Pfsense config
      Vlan 101 crated on igc3 interface
      Igc3.101 assigned to WAN
      WAN configured as PPPoE
      Username/pass copy passed from providers email
      MTU set to 1480 in both WAN and PPP gui

      I cannot get PPPoE connection, ever.
      Ifconfig shows MTU 1500 for PPPoE interface and 1488 for igc3.101, regardles of values entered in gui

      I'm pulling my hair here spent 4 ours trying all possible combinations on all 4 vr600 ports(according to TP-Link it should work on all ports)
      P.s I tried setting mtu though ssh and olifconfig but I'm gettin operation not permitted/denied
      Edit 2
      Re logged as root and changed mtu to 1480, no change, interesting that ssh wouldnt accept my 16character password manager generated password...

        Show your PPPoE connection log.

          Show your PPPoE connection log.

          I away from home network but fro the top of my head endless loop of

          Lcp link down event
          Something connection down
          Connecting to ""
          Timed out after 9 seconds
          Retrying xxx time

          Nothing google would give me any clue that something is wrong other than no connection

            Most probably : Your upstream device, the 'modem' can't sync with the ISP over the wire.
            It doesn't need a pfSense - or any other device - to do so, but it needs pfSense to hand over login credentials. And that's the only thing you can check on your side.
            So : bad wire, modem not feeling well, or ISP has 'some issues'.

              Unfortunately you're wrong,
              The moment I switch modem/router from bridge to ppoe I get link up within 2 seconds and for past 4 years I had maybe 2-3
              dropouts.

                So, ppoe is fine.

                But you opened with "PPPoE impossible to connect".

                pppoe isn't fine.

                Btw : 'bridge' = pppoe !?!

                ?

                I get it now : it never worked with pfSense - but it did with some other router ?

                Show your PPPoE connection log and system log.

                  I wasn't clear about my setup, sorry it was late.

                  I have a VDSL line
                  Tplink ar600 modem router

                  Moem connects fine when configured as "normal" ppoe internet connection
                  When modem is set to bridge mode it supposedly(I begin to doubt it) allows to use pfsense/router/pc to connect through it to ppoe using the same credentials.

                  Link pfsense box<-> modem is fine
                  Fact that I can't configure ppoe connection using pc connected directly to the modem makes me think modem is a problem, although tplink support swears by it and Reddit peeps seem to confirm.

                    I have seen on several forums that people constantly have problems with the correct configuration of this device in bridge mode. I'm not sure what the problem is, maybe different firmware for this tp-link device with different settings. What steps do you use to configure this device in bridge mode?

                      in advanced mode remove existing internet connection
                      Add new connection
                      Select bridge mode, tried both with enabling vtag and without
                      Click save

                      According to TP-Link support that's it
                      I added reboot for a good measure

                        Looks fine.
                        I don’t know, but the next step might be to try a dumb switch between TP-Link and PFSense and make a packet capture?
                        Also try capturing packets directly in PF, on the appropriate interface.

                          @w0w I have very limited testing window for next week or two.
                          Hour, maybe two if I'm lucky.
                          I'll try switch and wireshark packet capture

                            The TP-Link might still add the VLAN tag in bridge mode in which case you would not need it set in pfSense.

                            You shouldn't normally need anything else set for PPPoE. Especially just to see any LCP replies etc.

                              @stephenw10 I tried:
                              Pf pppoe with vlan tag <>modem bridge with and without vlan tag explicitly set
                              Pf pppoe without vlan tag <> modem bridge wit and without vlan tag explicitly set
                              Basically all combinations
                              I'll try them again while sniffing traffic

                                VLAN 101 looks like a UK DSL line? If so nothing special should be required. But I can say that BTs modems do the tagging themselves.

                                  @stephenw10 it is UK VDSL, openreach copper ,onestream ISP.

                                    Then should be nothing special required other than the VLAN. Seems likely the router is not bridging the PPPoE correctly.

                                      @stephenw10 I think I have a breakthrough.
                                      Modem Bridge with vlan tag, pfsense without vlan tag.

                                      Interface is up, got an IP address in familiar range but even pfsense itself cannot even ping DNS sever pulled from ISP, no route to host...

                                        Does the ppp log look correct? Something like:

                                        Dec 12 04:29:55 	ppp 	75336 	[wan] IPCP: LayerUp
                                        Dec 12 04:29:55 	ppp 	75336 	[wan] {my_ip_address} -> 172.16.13.252
                                        Dec 12 04:29:55 	ppp 	75336 	[wan] IFACE: Up event
                                        Dec 12 04:29:55 	ppp 	75336 	[wan] IFACE: Rename interface ng0 to pppoe0
                                        Dec 12 04:29:55 	ppp 	75336 	[wan] IFACE: Add description "PLUSNET" 
                                        

                                        Do you see the local and gateway address in Diag > Routes?

                                        Do you see anything blocked in the firewall logs?

                                          Left for an hour to eat and it works fine.
                                          I was probably too eager with testing.
                                          Although after moving both boxes to cabinet the booted an worked straight away(3 minutes max).

                                            @Sasquatchv you neglected to mention what ISP you are with. For PPPoE you only require the Router in Bridge mode then configure PPPoE on pfsense. Let the Router pass thru the modem and don’t configure PPPoE on the Router itself as the PPPoE with have two Open Sessions and majority of ISPs in UK, Ireland and Europe uses RAS/RAAS which will cause the Auth on PPPoE Session to fail.
