Deploy The Backup Zywall; Check Your Device Ha Setup - ZyXEL Communications ZyWALL USG 200 Series User Manual

7.15.4 Deploy the Backup ZyWALL

Connect ZyWALL B's lan1 interface to the LAN network. Connect ZyWALL B's
wan1 interface to the same router that ZyWALL A's wan1 interface uses for
Internet access. ZyWALL B copies A's configuration (and re-synchronizes with A
every hour). If ZyWALL A fails or loses its lan1 or wan1 connection, ZyWALL B
functions as the master.

7.15.5 Check Your Device HA Setup

To make sure ZyWALL B copied ZyWALL A's settings, you can log into ZyWALL B's
1
management IP address (192.168.1.5) and check the configuration. You can use
the Maintenance > File Manager > Configuration File screen to save copies
of the ZyWALLs' configuration files that you can compare.
To test your device HA configuration, disconnect ZyWALL A's lan1 or wan1
2
interface. Computers on LAN1 should still be able to access the Internet. If they
cannot, check your connections and device HA configuration.
Congratulations! Now that you have configured device HA for LAN1, you can use
the same process for any of the ZyWALL's other local networks. For example,
enable device HA monitoring on the DMZ interfaces and use an Ethernet switch to
connect both ZyWALLs' DMZ interfaces to your publicly available servers.
