VPort 251 User’s Manual System Configuration
NOTE
The 2nd FTP Server is a backup in case the 1st FTP Server fails to connect or has trouble
sending files.
NOTE
Whenever the system reboots, a system log will be sent by email or FTP to show the login status
of the VPort. The system log will be sent to the Sender email address if the SMTP server settings
are correct. To send the system log via FTP, the SMTP server should be erased since the E-mail
system is used by default to transmit the system log.
NOTE
For either e-mail or FTP, the information of the 1st server should be entered first. If the 1st
server is not set, the related FTP or email will be cancelled. Note that it may take time to connect
to the 2nd server after the first server fails, and it may affect some applications when adverse
conditions occur too often.
Dynamic DNS
DDNS (Dynamic Domain Name System) is a combination of DHCP, DNS, and client
registration. DDNS allows administrators to alias VPort’s dynamic IP address to a static hostname
in any of the domains provided by the DDNS service providers listed on VPort’s Network/DDNS
configuration page. DDNS makes it easier to access VPort from various locations on the Internet.
