Chapter 23 Tools ZyNOS (ZyXEL Network Operating System sometimes referred to as the "ras" file) is the system firmware and has a "bin" filename extension. Find this firmware at www.zyxel.com.With many FTP and TFTP clients, the filenames are similar to those seen next. ftp> put firmware.bin ras This is a sample FTP session showing the transfer of the computer file "firmware.bin" to the ZyXEL Device. ftp> get rom-0 config.cfg This is a sample FTP session saving the current configuration to the computer file "config.cfg". If your (T)FTP client does not allow you to have a destination filename different than the source, you will need to rename them as the ZyXEL Device only recognizes "rom-0" and "ras". Be sure you keep unaltered copies of both files for later use. The following table is a summary. Please note that the internal filename refers to the filename on the ZyXEL Device and the external filename refers to the filename not on the ZyXEL Device, that is, on your computer, local network or FTP site and so the name (but not the extension) may vary. After uploading new firmware, see the Status screen to confirm that you have uploaded the correct firmware version. Table 139 Filename Conventions FILE TYPE INTERNAL NAME EXTERNAL NAME DESCRIPTION Configuratio Rom-0 n File This is the configuration filename on the ZyXEL Device. Uploading the rom-0 file replaces the entire ROM file system, including your ZyXEL Device configurations, system-related data (including the default password), the error log and the trace log. *.rom Firmware Ras This is the generic name for the ZyNOS firmware on the ZyXEL Device. *.bin 23.3 File Maintenance Over WAN TFTP, FTP and Telnet over the WAN will not work when: 1 The firewall is active (turn the firewall off or create a firewall rule to allow access from the WAN). 2 You have disabled Telnet service in menu 24.11. 3 You have applied a filter in menu 3.1 (LAN) or in menu 11.5 (WAN) to block Telnet service. 4 The IP you entered in the Secured Client IP field in menu 24.11 does not match the client IP. If it does not match, the device will disconnect the Telnet session immediately. 304 P-2802H(W)(L)-I Series User's Guide
