Hello,
I came across this bug report while troubleshooting an OPNsense throughput
issue when using a VirtIO network card on Proxmox 8. 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 TrueNAS
Core server (NOT on the same Proxmox server).
I see that this issue has not been resolved since 2012. Is there ever a plan to
fix this? This behavior is still present on OPNsense 23.7.9 and therefore
FreeBSD 13.2.
Thanks
