You must subscribe to services on the backup ZyWALL before synchronizing it 
with the master ZyWALL.

Use this screen if you want the ZyWALL to get or to send updated IDP signatures, and 
configuration information in the virtual router.

You can only set up synchronization with other ZyWALLs of the same model 
running the same firmware version.

To access this screen, click Network > Device HA > Synchronize.

Figure 368   Network > Device HA > Synchronize

For synchronization, every ZyWALL in a virtual router should usually have the same 
Password, Synchronize From, and on port values. In addition, the management IP address 
must be in the same subnet as the interface (in other words, the virtual router). The following 
table describes the labels in this screen.  

Table 154   Network > Device HA > Synchronize

Password

Enter the password used to verify other ZyWALL routers during synchronization. 

This password is different than the one that is used for authentication in the VRRP 

group. Every ZyWALL in the virtual router must use the same password. If you 

leave this field blank, the password returns to its default setting “1234”.

Synchronize 

from

Enter the IP address or fully-qualified domain name (FQDN) of the router from 

which to get updated configuration and IDP signatures. Usually, you should enter 

the IP address or FQDN of a virtual router on a secure network.

on port

Enter the Secure FTP port number used by the ZyWALL you specified in 

Synchronize from. Usually, every ZyWALL in the virtual router should use the 

same port number. Otherwise, if the master ZyWALL changes, you might have to 

change this port number.
