I am trying to get everything running with this "correct" setup, but am running into the issues described. Up till now I was using the "incorrect" setup, where the IP addresses stayed with em0. This was working surprisingly well, except for IPv6 ndp needing s= ome prodding. But the "correct" setup, which I am trying to configure, results in connectivity problems under high load. This is the main issue. A side issue is that VirtualBox cannot attach to the bridge, but must be attached to em0 instead, which is a bridge member. Another unrelated issue are the additional difficulties I encounter with the native em0 driver as opposed to net/intel-em-kmod. Where in the manual pages does it say that a bridge must be set up in advan= ce and must then not be changed during its lifetime? -- Martin --=20 You are receiving this mail because: You are the assignee for the bug.=
