Unfortunately the only= way to achieve 10Gbps speed is to enable the HW Checksum Offloading option. Unfortunately, after activating it, access to servers on the same Proxmox server stops working and not only to them, but also for example to the True= NAS Core server (NOT on the same Proxmox server). I see that this issue has not been resolved since 2012. Is there ever a pla= n to fix this? This behavior is still present on OPNsense 23.7.9 and therefore FreeBSD 13.2.
