WARNING
: If an R3000 server is set up in the Target mode with a
NAT device between the target and source server, be sure that
ports 26262 and 26268 are open on the target server. This setup
is required so that the target server can communicate with the
source server.
Types of Synchronization Processes
Synchronization involves two types of processes: filtering
profile synchronization, and library synchronization.
Filtering Profile Synchronization Process
In the filtering profile synchronization process, if a filtering
change is made on the source server—whether the update
is a global, IP, NT, LDAP, minimum filtering bypass activa-
tion, or user profile update—the change is applied locally.
Once locally applied on the source server, this update is
sent to all target R3000 units. Each target server will then
immediately apply this filtering change. The result is that
profile updates occur on all R3000 units in near real time.
In the event that a target server is unable to communicate
with the source server, the target server will continue to run
the last known configuration it received from the source
server. The only exception to this scenario is that active
profiles—such as NT, LDAP, or override accounts—will not
run on the target server, since active profiles are timed out
after a specified period of time. However, all IP based
filters—such as the minimum filtering level, and the global
rule that was last received from the source server—will be
applied. When the target server resumes communication
with the source server, it will actively download and apply
the latest running configuration from the source server.
