(for management Interface) will be considered, e.g., 192.168.1.2 has higher
priority than 192.168.1.3…, etc.
(c) Authentication Key: enter the same authentication key on all the members.
(d) Management Interface: the packets for communication (including deciding the
primary, configuration sync, and some maintenance…,etc) between members will
be sent in the management interface, in other word, clients in other LAN subnet
won't be able to see these packets. In order to have best communication and for
security purpose, we recommend to choose an interface that is less possible to
have interruption for the communication (loop/broadcast storm from other LAN
clients…). In our scenario, we reserve LAN 1 for High Availability only, and put all
other LAN clients in LAN2~LAN5.
(e) Update DDNS: for dynamic WAN IP users, enable this function so once the
secondary router becomes primary and dials up the WAN, it will also update its
new WAN IP address to the same DDNS profile, so your network will be accessible
with the same DDNS domain.
(f) Syslog: enable to show all the High Availability related logs in syslog.
(g) Enable the LAN Subnet to join High Availability. Any existing LAN without joining
High Availability will not be served with hardware redundancy.
Virtual IP: name the virtual IP here, please note that the virtual IP can NOT be the
same with any member LAN IP.
2. Enable Configuration Sync and set the Sync Interval. Default is every 15 minutes.
3. Configure High Availability on the secondary router. Mind that the Priority should be
lower than the primary router. Besides priority, all other settings should be the same.
