File
Rom-0 *.rom This is the configuration filename on the
ZyWALL. Uploading the rom-0 file replaces
the entire ROM file system, including your
ZyWALL configurations, system-related data
(including the default password), the error
log and the trace log.
Firmware Ras *.bin This is the generic name for the ZyNOS
firmware on the ZyWALL.
21.2 Backup Configuration
The ZyWALL displays different messages explaining different ways to backup,
restore and upload files in menus 24.5, 24.6, 24. 7.1 and 24.7.2; depending on
whether you use the console port or Telnet.
Option 5 from Menu 24 - System Maintenance allows you to backup the current ZyWALL configuration
to your computer. Backup is highly recommended once your ZyWALL is functioning properly. FTP is the
preferred methods for backing up your current configuration to your computer since it is faster. You can
also perform backup and restore using menu 24 through the console port. Any serial communications
program should work fine; however, you must use Xmodem protocol to perform the download/upload and
you don’t have to rename the files (see section 21.1).
Please note that terms “download” and “upload” are relative to the computer. Download means to transfer
from the ZyWALL to the computer, while upload means from your computer to the ZyWALL.
