I've a running bridge on FreeBSD 8.2 cloned_interfaces="bridge0" autobridge_interfaces="bridge0" autobridge_bridge0="fxp0 fxp1" ifconfig_bridge0="inet 10.100.32.15/24 up" ifconfig_fxp0="up" ifconfig_fxp1="up" this one running for years without a hitch. But it's quite old so I'm building a replacement on FreeBSD 11.1 I've copied these setting and the firewall configs as well. cloned_interfaces="bridge0" autobridge_interfaces="bridge0" autobridge_bridge0="em0 em1" ifconfig_bridge0="inet 10.100.32.18/24 up" ifconfig_em0="up" ifconfig_em1="up" The new bridge starting up does bridge the traffic but the bridge server can't communicate. here is the output from ifconfig em0: flags=8943 metric 0 mtu 1500 options=9b ether 08:00:27:53:57:a0 hwaddr 08:00:27:53:57:a0 nd6 options=29 media: Ethernet autoselect (1000baseT ) status: active em1: flags=8943 metric 0 mtu 1500 options=9b ether 08:00:27:12:e7:9e hwaddr 08:00:27:12:e7:9e nd6 options=29 media: Ethernet autoselect (1000baseT ) status: active lo0: flags=8049 metric 0 mtu 16384 options=600003 inet6 ::1 prefixlen 128 inet6 fe80::1%lo0 prefixlen 64 scopeid 0x3 inet 127.0.0.1 netmask 0xff000000 nd6 options=21 groups: lo bridge0: flags=8843 metric 0 mtu 1500 ether 02:3d:73:0f:54:00 inet 10.100.32.18 netmask 0xffffff00 broadcast 10.100.32.255 nd6 options=9 groups: bridge id 00:00:00:00:00:00 priority 32768 hellotime 2 fwddelay 15 maxage 20 holdcnt 6 proto rstp maxaddr 2000 timeout 1200 root id 00:00:00:00:00:00 priority 32768 ifcost 0 port 0 member: em1 flags=143 ifmaxaddr 0 port 2 priority 128 path cost 2000000 member: em0 flags=143 ifmaxaddr 0 port 1 priority 128 path cost 2000000 if delete the bridge and configure em0 directly ip works. anyone a idea what I'm doing wrong.
