Excluding TCP/UDP traffic from replication
In configurations that handle heavy traffic, it may be necessary to optimize the traffic to replicate.
Some categories of traffic can be excluded from synchronization in the filter policy, by unselecting the option Synchronize this connection between firewalls (HA), which is selected by default (Action > Advanced properties in the filter rule dialog box):
The connections that match this rule will therefore not be replicated between members of the cluster.
