Setup
Typical HA Cluster Network Connections
The illustration below shows the arrangement of typical HA Cluster connections in a network. All
interfaces on the master unit would normally also have corresponding interfaces on the slave unit
and these would be connected to the same networks. This is achieved by connecting the same
interfaces on both master and slave via a separate switch (or broadcast domain) to other network
portions.
In the scenario shown above, the lan interface on the master and the lan interface on the slave
would be connected to the same switch which then connects to an internal network. Similarly the
wan interface on the master and the wan interface would connect to a switch which in turn connects
to the external Internet.

To set up an HA cluster manually, the steps are as follows:
1. Connect to the master unit with the WebUI.
Note: The illustration shows a crossover cable sync connection
The illustration above shows a direct crossover cable connection between the sync
interfaces of each unit. This connection could, instead, be via a switch or broadcast
domain.
