Hello, dear All I have some bridges (FB 8.4 on-board) which work perfect, but have problem with disk replacing in mirror (a srv has to be stopped for replacing of disk). We installed new FB 12.0-stable and met a problem - all packets drops in dummynet subsystem. It looks that a packet goes into a pipe and doesn't return back from there Income int - ix1 Outgoing - ix0 For test I send icmp from 10.10.10.1 (ix1 side) to 10.10.10.10 (ix0 side), tcpdump shows incoming packets at ix1: listening on ix1, link-type EN10MB (Ethernet), capture size 262144 bytes 19:28:06.339329 IP 10.10.10.1 > 10.10.10.10: ICMP echo request, id 30347, seq 2675, length 64 19:28:07.402915 IP 10.10.10.1 > 10.10.10.10: ICMP echo request, id 30347, seq 2676, length 64 19:28:08.466494 IP 10.10.10.1 > 10.10.10.10: ICMP echo request, id 30347, seq 2677, length 64 ipfw pipe 100 config bw 15Mbit/s queue 465 00100 1637 137508 pipe 100 ip from any to 10.10.10.0/24 out via ix0 00110 0 0 allow ip from any to 10.10.10.0/24 out via ix0 ifconfig_ix0="up -tso4 -tso6 -lro -vlanhwtso" ifconfig_ix1="up -tso4 -tso6 -lro -vlanhwtso" cloned_interfaces="bridge0" ifconfig_bridge0="addm ix0 addm ix1 up" net.inet.ip.fw.enable: 1 net.inet.ip.fw.one_pass: 0 net.link.ether.ipfw: 0 net.link.bridge.ipfw: 1 net.link.bridge.allow_llz_overlap: 0 net.link.bridge.inherit_mac: 0 net.link.bridge.log_stp: 0 net.link.bridge.pfil_local_phys: 0 net.link.bridge.pfil_member: 1 net.link.bridge.ipfw_arp: 0 net.link.bridge.pfil_bridge: 0 net.link.bridge.pfil_onlyip: 0 I am ready to publish any additional info to investigate the problem.
