Table 4-1 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

Type how many minutes a management session (either via the web configurator or

Inactivity Timer

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 machine before you can access it. The ZyWALL 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

Select From ISP if your ISP dynamically assigns DNS server information (and the

 

ZyWALL's WAN IP address). The field to the right displays the (read-only) DNS server

Second DNS

IP address that the ISP assigns.

Server

Select User-Definedif you have the IP address of a DNS server. Enter the DNS

 

server's IP address in the field to the right. If you chose User-Defined, but leave the IP

Third DNS

address set to 0.0.0.0, User-Definedchanges to None after you click Apply. If you set

Server

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.
