i was just going to suggest this... for the benefit of the mailing list, bridge(4) effectively turns every interface you add to a bridge into two ports: one that faces the IP stacks and another that faces the physical connection it has. if this sounds confusing, then yes, it is. with veb and vport, only vport interfaces provide a connection between the ip stack and the layer2 network built out veb and physical interfaces. if you do try this with veb/vport, you should be able to tcpdump on athn0 and see that dhcp requests come in, then tcpdump on veb should show them crossing the bridge, and then tcpdump on vport0 should show them going toward the network stack and dhcpd. also, you're bridge(4) interface isn't UP in the output below, so it's not going to carry packets from athn0 to vether0. > > > vether0: flags=8943<UP,BROADCAST,RUNNING,PROMISC,SIMPLEX,MULTICAST> mtu 1500 > > lladdr fe:e1:ba:d0:cd:4a > > index 9 priority 0 llprio 3 > > groups: vether > > media: Ethernet autoselect > > status: active > > inet 192.168.1.1 netmask 0xffffff80 broadcast 192.168.1.127 > > athn0: flags=8943<UP,BROADCAST,RUNNING,PROMISC,SIMPLEX,MULTICAST> mtu 1500 > > lladdr 00:26:82:61:87:c9 > > index 5 priority 4 llprio 3 > > groups: wlan > > media: IEEE802.11 autoselect mode 11g hostap > > status: active > > ieee80211: nwid TEST chan 2 bssid 00:26:82:61:87:c9 -58dBm wpakey > > wpaprotos wpa2 wpaakms psk wpaciphers ccmp wpagroupcipher ccmp > > bridge0: flags=0<> mtu 1500 > > index 8 llprio 3 > > groups: bridge > > priority 32768 hellotime 2 fwddelay 15 maxage 20 holdcnt 6 proto > > rstp > > designated: id 00:00:00:00:00:00 priority 0 > > athn0 flags=3<LEARNING,DISCOVER> > > port 5 ifpriority 0 ifcost 0 > > em1 flags=3<LEARNING,DISCOVER> > > port 2 ifpriority 0 ifcost 0 > > vether0 flags=3<LEARNING,DISCOVER> > > port 9 ifpriority 0 ifcost 0 > > Addresses (max cache: 100, timeout: 240): >
