Table 19-1 General Setup Menu Field
FIELD
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].
First System DNS
DNS (Domain Name System) is for mapping a domain name to its
Server
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 Contivity C221
Second System
uses a system DNS server (in the order you specify here) to resolve
DNS Server
domain names for VPN, DDNS and the time server.
Press [SPACE BAR] and then [ENTER] to select an option. Select
Third System DNS
From ISP if your ISP dynamically assigns DNS server information
Server
(and the Contivity C221's WAN IP address). The IP Address field
below displays the (read-only) DNS server IP address that the ISP
assigns. If you chose From ISP, but the Contivity C221 has a fixed
WAN IP address, From ISP changes to None after you save your
changes. If you select From ISP for the second or third DNS server,
but the ISP does not provide a second or third IP address, From ISP
changes to None after you save your changes.
Select User-Defined if you have the IP address of a DNS server.
Enter the DNS server's IP address in the field to the right. 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.
