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].

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.
