The following should do to build a bridge=20 ifconfig eth0 down # brctl addbr br0 # addif br0 eth0 # ifconfig eth0 0.0.0.0 up # ifconfig br0 192.168.1.1 up Ok now let's see brctl show bridge name bridge id STP enabled interfaces br0 8000.001d7dd106bd no eth0 looks fine to me then=20 ifconfig br0=20 br0 Link encap:Ethernet Hardware Adresse 00:1d:7d:d1:06:bd=20=20 inet Adresse:192.168.1.1 Bcast:192.168.1.255 Maske:255.255.255.0 inet6-Adresse: fe80::21d:7dff:fed1:6bd/64 G=FCltigkeitsbereich:Ve= rbindung UP BROADCAST RUNNING MULTICAST MTU:1500 Metrik:1 RX packets:1 errors:0 dropped:0 overruns:0 frame:0 TX packets:23 errors:0 dropped:0 overruns:0 carrier:0 Kollisionen:0 Sendewarteschlangenl=E4nge:0=20 RX bytes:192 (192.0 B) TX bytes:4420 (4.3 KiB) looks also fine to me but then: ping 192.168.1.10 PING 192.168.1.10 (192.168.1.10) 56(84) bytes of data. ping: sendmsg: Operation not permitted ping: sendmsg: Operation not permitted ping: sendmsg: Operation not permitted I can not make any sens why ping can fail. so either I misread all the docs or something is foul.
