Physical L-Servers for NS Appliances are targets of Disaster Recovery.
However, note the following points:
When using NS Appliances as network devices, prepare physical L-Servers for NS Appliances based on the units in which switchover will be performed.
Specify the name of the physical server used to create the physical L-Server of NS Appliance. Use the same physical server names between sites.
As was done for the other network devices, create an NS Appliance at the backup site and register it as a network device beforehand.
"backup of configurations" and "copying of configurations", both of which are performed for firewall units, are not necessary.
For details, refer to "DR Option Instruction".
