      I can't explain this. So you are using PPPoE (over vtnet) and clients on LAN can not reach internet?

        @w0w Yes.
        And at the same time, clients on the same hypervisor, bound to the same bridge to lan, using virtio, can reach the Internet fine.

        Also clients on the physical lan, can ping the Internet over pppoe.

          I was able to reproduce this bug: I installed 25.07.1, restored the configuration, verified that LAN clients had Internet access, and then upgraded to the latest RC. After the upgrade, the clients no longer had Internet access.
          That's fun...

                @w0w So we definitely have an issue here. It can't be a configuration issue, and certainly NOT a firewall rules issue.
                But I remain clueless where to look. (Besides the fact that I need to revert for practical reasons, and running another pf plus vm in parallel for testing has licensing issues too)

                  I dug a bit deeper. I compared the system that was installed from scratch with the one that was upgraded. Of course, things went a bit sideways, but overall there are noticeable differences in both libraries and some binaries, which raises some questions — although in general this could simply be a consequence of the FreeBSD version upgrade.
                  By the way, have you tried installing it using the Netgate installer?

                    @w0w So you say that by doing a clean default install with netgate installer AND restoring the config would work in latest RC?

                    Can't check this right now, someone might shoot me and it would be netgates fault 😱

                      It worked once at least, but I didn’t try it again 😊

                        @w0w Brewing... I know in a while

                        Nada. Issue remains the same. I installed directly into latest rc 25.11.r.20251126.1732
                        and restored config.

                        Only ping over pppoe.

                          ok… thats interesting…

                          ifconfig vtnet0 -rxcsum -txcsum -rxcsum6 -txcsum6 -vlanhwtag -vlanhwcsum
                          

                          Try this on LAN interface. Hope this works for you...

                          I just compared ifconfig output for both working and non working VMs and looks like working VM on every interface have options=880008<VLAN_MTU,LINKSTATE,HWSTATS>
                          So I applied it to the pppoe parent - still no go... and then I've tried LAN interface and it worked for me.

                              Please show your ifconfig output for LAN and pppoe parent interface.

                                @w0w I have now created a fresh default install
                                Directly install 25.11rc from netgate installer , configured everything by the gui just for a single lan, and a single pppoe connection.

                                Automatic outbound nat etc. No changes anywhere

                                ping works, everything else on physical lan fails (miserably)
                                pfsense (and anything on virtual) can install packages, and has full Internet

                                have tried disabling checksums too. No dice

                                ifconfig vtnet1
                                vtnet1: flags=1008843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST,LOWER_UP> metric 0 mtu 1500

                                As a side note, when restoring configuration to a fresh install 25.11rc, all packages got reinstalled, however the widget says no packages.
                                I have tried removing it and adding again. Nada.
                                Tried adding a new package (from gui), package got installed the widget insists. No packages installed.

                                Steps to reproduce. Install fresh pfplus 25.11rc, restore config that has package widget and some packages, wait for the packages reinstallation, and voila !

                                    All vlan configuration is handled at the hypervisor level.
                                    pf sees only virtual interfaces.

                                      I kinda screwed up… I forgot to mention that this ix0 is part of a LAGG interface, and the LAN itself is using that LAGG. This shouldn’t really affect anything, but I’ll check if that’s the issue. Also, I don’t remember changing any settings for this NIC on the host, I think I left it as is.

                                        Configured LAN to use ix0 directly — nothing changed.

                                          @netblues said in pfSense VM on Proxmox: PPPoE only works when parent NIC is PCI passthrough — virtual NIC breaks LAN→WAN traffic:

                                          JUMBO_MTU

                                          Hmm… I don't see any jumbo settings on my vtnet interfaces, did you change something? VM setiings? Nonstandard MTU?

                                          Now I have configured it directly for both pppoe and LAN

                                          Ok, I've changed MTU to 9000 in proxmox for the LAN card/bridge/vtnet

                                            @w0w I see minor differences on the physical kvm interface, but I haven't done anything special, its at defaults.

                                            The mtu has been adjusted to 1508, but that can't be the issue. In any case, the brigded interfaces all use 1500 as mtu.

                                            As is, the same bridges are used at the same time by pfpls @25.07 pfplus @25.11rc and pfCE 2.8.1 with multiple pppoe connections over the same parent vlam.

                                            Only new rc fails to work as described above.
