Hardware failover
-
Hi!
If there will be any kind of fail on any interface except NIC with CARP/Sync, then will pfSense manage it (turn to backup server)?

Anyone?

Complete failover to the backup machine is controlled by net.inet.carp.preemt = 1, which is the default for PFSense as far as I know (at least on our 2.0.1 production machines).
So yes, should any CARP VIP lose link (or rather, should the backup machine stop receiving the heartbeat from the primary), the backup will bring up the VIPs on all interfaces.
I'm not quite sure what you're asking here, but an initial setup to get you started with CARP is demonstrated here: http://doc.pfsense.org/index.php/Configuring_pfSense_Hardware_Redundancy_(CARP)
