--- Comment #9 from Marcus Haarmann <mhaarm...@midoco.de> --- Thanks for the hint with the old network cards, I will suggest exchanging the NIC with a new one. Maybe this helps. I am not sure how old this machine is. We have tried switching off and on the hardware I now posted the same request to the pfsense team. Maybe they have modified the kernel at the tcp level. -- You are receiving this mail because: You are the assignee for the bug.
