Problem only with UDP. I can only do the experiment on Monday, otherwise I might lose access to the hardware. This configuration worked fine on the September build FreeBSD 14.3-STABLE without any changes. It was only when I updated to the December build that problems appeared. --=20 You are receiving this mail because: You are the assignee for the bug.=
