Hi. I have a router running 6.4R that does not forward packets if I disable PROMISC on the interface. Hardware is a Dell PE with two Intel 82541EI chipsets (if_em). I have a number (~100) of vlan-interfaces on em0. Everything works as aexpected = if I turn on PROMISC on em0 but forwarding stops if I disable it, I can still communicate with the router directly on the same logical network (for example pinging interface adress on a vlan_if from a client on that = vlan) but all forwarding stops. Some info: net.inet.ip.forwarding: 1 net.inet.ip.fastforwarding: 0 (enableing this does not help) net.inet.tcp.recvspace=3D1048576 net.inet.tcp.sendspace=3D1048576 kern.ipc.maxsockbuf=3D16777216 I use PF for filtering and disableing this does not help either. Anyone with a clue? //JO
