There was found an ipfw rule which drops packets to local named daemon. It was antispoofing rule. So there is a problem: vr0 is an interface with ip 192.168.1.201 bind listens at 192.168.1.201:53 When i try to do any resolving, system sends packets at 192.168.1.201:53 trough lo0, so ipfw antispoof rule drops it coz of missinterfacing. netstat -rn shows stright pass for all 192.168.1 subnet : LINK#2 (which is vr0) Now i just skip this rule and all works well. Note, that 5.3 with its older bind9 was OK with it. The problem started exactly after upgrading kernel and world. >How-To-Repeat: I havent any thoughts. >Fix: >Release-Note: >Audit-Trail: >Unformatted:
