Kernel: FreeBSD 13.1-RELEASE-p8 GENERIC amd64 Issue: vlan traffic not in the jail Weird issue today... I have a bridge with on the host, two jails, and a vlan in the jail. The jails were networking just fine with their native vlan (1), but the host would not pass 802.1q traffic to the jail. If I created the vlan91 on the host, that would 'wake up vlan awareness on the bridge'. I could then destroy the vlan91 on the host, and the jail still passes traffic. The Workaround: host#ifconfig vlan91 create vlan 91 vlandev igb1 10.1.1.1/28; ifconfig vlan91 destroy Maybe something wrong with the bridge spanning tree implementation? It's like that bridge was created before the vlans, and the non-native vlans are pruned.
