Hi! I have faced such problem: Has established the bridge on FreeBSD 6.3 and the module if_bridge. But at me the traffic passing through the bridge is not filtered. Here so all looks: Code: #ifconfig fxp0: flags=8943<UP,BROADCAST,RUNNING,PROMISC,SIMPLEX,MULTICAST> mtu 1500 options=8<VLAN_MTU> ether 00:a0:c9:65:c1:35 media: Ethernet autoselect (100baseTX <full-duplex>) status: active fxp1: flags=8943<UP,BROADCAST,RUNNING,PROMISC,SIMPLEX,MULTICAST> mtu 1500 options=8<VLAN_MTU> ether 00:90:27:85:b7:95 media: Ethernet autoselect (100baseTX <full-duplex>) status: active rl0: flags=8802<BROADCAST,SIMPLEX,MULTICAST> mtu 1500 options=8<VLAN_MTU> ether 4c:00:10:60:67:ca media: Ethernet autoselect status: no carrier re0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500 options=1b<RXCSUM,TXCSUM,VLAN_MTU,VLAN_HWTAGGING> inet 192.168.5.28 netmask 0xffffff00 broadcast 192.168.5.255 ether 00:0f:ea:f9:a6:ff media: Ethernet autoselect (100baseTX <full-duplex>) status: active plip0: flags=108810<POINTOPOINT,SIMPLEX,MULTICAST,NEEDSGIANT> mtu 1500 lo0: flags=8049<UP,LOOPBACK,RUNNING,MULTICAST> mtu 16384 inet6 fe80::1%lo0 prefixlen 64 scopeid 0x6 inet6 ::1 prefixlen 128 inet 127.0.0.1 netmask 0xff000000 bridge0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500 ether b6:c3:a2:cc:06:65 id 00:00:00:00:00:00 priority 32768 hellotime 2 fwddelay 15 maxage 20 holdcnt 6 proto stp maxaddr 100 timeout 1200 root id 00:00:00:00:00:00 priority 32768 ifcost 0 port 0 member: fxp1 flags=143<LEARNING,DISCOVER,AUTOEDGE,AUTOPTP> member: fxp0 flags=143<LEARNING,DISCOVER,AUTOEDGE,AUTOPTP> #sysctl -a |grep bridge net.link.ether.bridge_cfg: net.link.ether.bridge_ipfw: 1 net.link.ether.bridge_ipf: 0 net.link.ether.bridge.config: net.link.ether.bridge.enable: 0 net.link.ether.bridge.predict: 0 net.link.ether.bridge.dropped: 0 net.link.ether.bridge.packets: 0 net.link.ether.bridge.ipfw_collisions: 0 net.link.ether.bridge.ipfw_drop: 0 net.link.ether.bridge.copy: 0 net.link.ether.bridge.ipfw: 1 net.link.ether.bridge.ipf: 0 net.link.ether.bridge.debug: 0 net.link.ether.bridge.version: 031224 net.link.bridge.pfil_onlyip: 0 net.link.bridge.ipfw_arp: 0 net.link.bridge.pfil_bridge: 1 net.link.bridge.pfil_member: 1 net.link.bridge.pfil_local_phys: 1 net.link.bridge.log_stp: 0 net.link.bridge.ipfw: 1 #ipfw show ipfw show 00100 0 0 allow ip from 85.159.31.54 to any layer2 via bridge0 00200 6 5885 allow ip from 85.159.31.54 to any layer2 00300 0 0 allow ip from 85.159.31.54 to any layer2 via fxp1 00400 0 0 allow ip from 85.159.31.54 to any layer2 via fxp0 00500 0 0 allow ip from 85.159.31.54 to any via fxp0 00600 0 0 allow ip from 85.159.31.54 to any layer2 via bridge0 mac-type 0x8100 00700 0 0 allow ip from 85.159.31.54 to any via bridge0 mac-type 0x8100 00800 0 0 allow ip from 85.159.31.54 to any via fxp0 mac-type 0x8100 00900 0 0 allow ip from 85.159.31.54 to any via fxp1 mac-type 0x8100 01000 0 0 allow ip from 85.159.31.54 to any via bridge0 layer2 MAC any any mac-type 0x8100 01100 0 0 allow ip from 85.159.31.54 to any via bridge0 MAC any any mac-type 0x8100 01200 0 0 allow ip from 85.159.31.54 to any via bridge0 mac-type 0x8100 01300 10874732 657168582 count ip from any to any layer2 via bridge0 01400 82562 7154845 count ip from any to any not layer2 via bridge0 01500 10611069 640854269 count ip from any to any layer2 via bridge0 mac-type 0x8100 01600 77929 6682967 count ip from any to any layer2 via bridge0 mac-type 0x0800 01700 0 0 count ip from any to any not layer2 via bridge0 mac-type 0x8100 01800 0 0 count ip from any to any not layer2 via bridge0 mac-type 0x0800 01900 0 0 count ip from any to any not layer2 via bridge0 mac-type 0x8100 02000 0 0 count ip from 85.159.31.54 to any layer2 via bridge0 mac-type 0x8100 02100 0 0 count ip from 85.159.31.54 to any layer2 via bridge0 mac-type 0x0800 02200 0 0 count ip from 85.159.31.54 to any not layer2 via bridge0 mac-type 0x8100 02300 0 0 count ip from 85.159.31.54 to any not layer2 via bridge0 mac-type 0x0800 02400 640285 437872365 count ip from any to any layer2 via fxp0 02500 4019 426922 count ip from any to any not layer2 via fxp0 02600 621668 426064356 count ip from any to any layer2 via fxp0 mac-type 0x8100 02700 1091 142307 count ip from any to any layer2 via fxp0 mac-type 0x0800 02800 0 0 count ip from any to any not layer2 via fxp0 mac-type 0x8100 02900 0 0 count ip from any to any not layer2 via fxp0 mac-type 0x0800 65535 146210062 61716361162 allow ip from any to any The scheme of connection: <--cisco-trunk--><--bridge--><--cisco-trunk--> how you can see most packedges do not upper layer2. I wish to know, how I can filter them? If i use instead of one Catalyst simple hub, packages are filtered. In what there can be a problem?
