FIELD
DESCRIPTION
System Name
Choose a descriptive name for identification purposes. It is recommended you 
enter your computer’s “Computer name” in this field. 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. You can go to menu 24.8 and type 
"sys domain name" to see the current domain name used by your router.
The domain name entered by you is given priority over the ISP assigned 
domain name. If you want to clear this field just press [SPACE BAR] and then 
[ENTER].

Server
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 ZyAIR uses a system DNS server (in the order 
you specify here) to resolve domain names for VPN, DDNS and the time 
server.
Press [SPACE BAR] and then [ENTER] to select an option. Select From ISP if 
your ISP dynamically assigns DNS server information (and the ZyAIR's WAN 
IP address). The IP Address 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 IP Address field. If you select User-Defined
but leave the IP address set to 0.0.0.0, User-Defined changes to None after 
you save your changes. If you set a second choice to User-Defined, and enter 
the same IP address, the second User-Defined changes to None after you 
save your changes.
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.
Edit Dynamic DNS
Press [SPACE BAR] and then [ENTER] to select Yes or No (default). Select 
Yes to configure Menu 1.1: Configure Dynamic DNS discussed next.
When you have completed this menu, press [ENTER] at the prompt “Press ENTER to Confirm…” to 
save your configuration, or press [ESC] at any time to cancel.
