Like the packet was eaten before it made it into the child vlan interface. Activating the debug code shows that neither the bridge fordwarding routine wasn't catching the packets. All vlans were child of the same parent interface (a RealTek) and they were all configuren in the same bridge cluster. Either with configured IPs or without (just up'ed the intefaces). I might have botched the interfaces by mutiple reconfigurations, but I just would like to know if other people had success with bridged VLAN interfaces (yes, it sounds a bit weird if you think of it :) ). -- Adrian Penisoara Ady (@freebsd,ady.ro)
