Probably yes. Are you doing NAT and each link has NAT to a different
IP address? In this case you can't achieve such level of redundancy
that TCP sessions will survive failure of the one link.

T> What arp balance do exactly? It will be good for my?

You probably don't need it.

T> And... I need to use ifstated?

Only if you need to do something in case of CARP changing state.
