      I know this is most likely the problem is on the Proxmox side, but I wanted to bring attention to this issue. Maybe someone here has encountered it before.

      I don't think that the current version of pfSense and Proxmox require disabling hardware checksum offload and hardware TCP segmentation offload on the physical linux (=proxmox) side, unless there is a new bug.

      See https://forum.proxmox.com/threads/pfsense-disconnects-every-few-minutes-when-using-virtio-nic.116826/

        Update: maybe this IS a pfsense issue (more specifically, FreeBSD 12.x), despite q35 chipset not being in use in my case?

          I"ve no issues on KVM with i440 chipset and hardware checksum offloading enabled.

            If there is indeed a FreeBSD bug, since Proxmox doesn't offer virtio-transitional, I might have to use another adapter: vmxnet3 works so far, speeds are not like virtIO but it allows me to wait longer for a solution.

                Upgrading to pfSense 23.01/FreeBSD 14 (from 22.05/FreeBSD 12), solved the issue. Don't know if it was pfSense or FreeBSD, but it surely wasn't a Proxmox issue.

                  Hi,

                  I have pfSense 22.05 virtualized in proxmox 7.3: I had strange network performance issue with it and also with a plain debian install.

                  Turned out issue was NIC used (intel 210) belonged to a PCIE card, while in proxmox grub I had pcie passthrough option active: once removed all back to normal.
                  Not sure if that could be related though
