Figure 34-43. Configuration > Peers page Redundancy tab
When configuring redundancy, the ZoneRanger becoming redundant (the target ZoneRanger)
gets its settings and information from the source ZoneRanger specified in the Source
ZoneRanger for Redundancy field. The Polling Interval defines how frequently each
redundant ZoneRangers verifies the availability of all the other redundant ZoneRangers. The
passcodes must match between the source and target ZoneRangers. Enabling redundancy will
result in a restart of the target ZoneRanger.
Once redundancy has been established between ZoneRangers, the Configuration > Peers page
Redundancy tab will list all redundant ZoneRangers and the status of each ZoneRanger.
Configuring virtual IP
A virtual IP address may be shared by redundant ZoneRangers. A virtual IP address is a
secondary IP address which one of the redundant ZoneRangers is configured to support. If that
ZoneRanger becomes unavailable, another ZoneRanger will automatically begin supporting that
IP address. This functionality allows for ZoneRanger managed devices to be configured with a
single IP address for forwarding rather than the primary ZoneRanger IP address. Thus, if the
primary IP address of the ZoneRanger needs to be changed, the ZoneRanger managed devices
will not need to be updated with a new IP address. The Configuration > Peers page Virtual IP
tab is used to establish the virtual IP address of the redundant ZoneRangers.
Figure 34-44. Configuration > Peers page Virtual IP tab
The virtual IP address may be created on either eth0 or eth1 on the ZoneRanger but that must be
consistent on all redundant ZoneRangers.
