Table 8 System General Setup
LABEL DESCRIPTION
System Name Choose a descriptive name for identification purposes. It is recommended you
enter your computer’s “Computer name” in this field (see the Wizard Setup
chapter for how to find your computer’s name). This name can be up to 30
alphanumeric characters long. Spaces are not allowed, but dashes “-” and
underscores "_" are accepted.
Domain Name Enter the domain name (if you know it) here. If you leave this field blank, the ISP
may assign a domain name via DHCP.
The domain name entered by you is given priority over the ISP assigned domain
name.
Administrator
Inactivity Timer
Type how many minutes a management session (either via the web configurator
or SMT) can be left idle before the session times out. The default is 5 minutes.
After it times out you have to log in with your password again. Very long idle
timeouts may have security risks. A value of "0" means a management session
never times out, no matter how long it has been left idle (not recommended).
System DNS Servers (if applicable)
DNS (Domain Name System) is for mapping a domain name to its corresponding IP address and vice
versa. The DNS server is extremely important because without it, you must know the IP address of a
computer before you can access it. The Prestige uses a system DNS server (in the order you specify
here) to resolve domain names for VPN, DDNS and the time server.
First DNS Server
Second DNS Server
Third DNS Server Select From ISP if your ISP dynamically assigns DNS server information (and the
Prestige's WAN IP address). The field below displays the (read-only) DNS server
IP address that the ISP assigns.
Select User-Defined if you have the IP address of a DNS server. Enter the DNS
server's IP address in the field below. If you chose User-Defined, but leave the IP
address set to 0.0.0.0, User-Defined changes to None after you click Apply. If
you set a second choice to User-Defined, and enter the same IP address, the
second User-Defined changes to None after you click Apply.
Select None if you do not want to configure DNS servers. If you do not configure
a system DNS server, you must use IP addresses when configuring VPN, DDNS
and the time server.
