I can't get either box to become master for 192.168.1.10 If I do a tcpdump on the em0 interface on the boxes, I see multicast traffic out on em0 on test1 and I see multicast traffic from test1 on em0 of test2. The only firewall rules are pass in all and pass out all. On test1(should be the master): > netstat -ssp carp carp: 40572 packets received (IPv4) 326 discarded for bad vhid 160550 packets sent (IPv4) On test2(the backup); > netstat -ssp carp carp: 134298 packets received (IPv4) I'm hoping someone out here can help because this is driving me crazy and I can not even think about this for a production environment if I can't get it working in very simple test setup. Thanks, Chris
