IMPORTANT:
need to open (TCP) ports 9387 (Command protocol) and 9388 (Data protocol) to allow the

Bandwidth Limiting

This tab allows users with an Admin login to apply a general bandwidth setting and to configure
bandwidth limiting windows.
Bandwidth limiting can be used to avoid saturating the WAN with low bandwidth replication, thus

of 2Mbps per concurrent job is recommended. At least 512kbps per concurrent job is required
for reliable operation. These limits apply to all outbound replication jobs from this local appliance.

sync issue is shown in the Issue tab, and an event is generated, resulting in an entry in the
user Event Log, and also an email and/or an SNMP trap if the appliance is configured to
send these. These notifications are in addition to a standard notification email sent whenever
a mapping first becomes unsynchronized and another when synchronization is achieved.
Replication ports should only be changed if replication is blocked by a router on the WAN.
They must be the same on both source and target appliances. If in doubt, do NOT change
them.
If replication needs to take place through a firewall, the network administrator will
