DNS (Domain Name System):
DNS is used to map a domain name to its corresponding
IP address and vice versa. The DNS server is extremely important.
Without it, you must
know the IP address of a computer before you can access it. The Residential Gateway
uses a system DNS server (in the order you specify here) to resolve domain names for
VPN, DDNS and the time server.
Primary DNS Server:
Specify the primary IP address of the DNS server.
Secondary DNS Server:
Specify the secondary IP address of the DNS server.
Ping from WAN:
Blocking the Ping may provide some extra security from hackers. Tick
this checkbox to allow the WAN port to be pinged.
2. DHCP:

DHCP Server Settings
DHCP
(Dynamic Host Configuration Protocol, RFC 2131 and RFC 2132) allows individual
clients to obtain TCP/IP configuration at start-up from a server. You can configure this
gateway as a DHCP server or disable it. When the gateway is configured as a server, it
provides the TCP/IP configuration for clients. If DHCP service is disabled, you must have
another DHCP server on your LAN; otherwise, the computer must be manually configured.
Tick
“
DHCP server
”
checkbox
to
enable or disable the DHCP server. If
Enable
is checked
and a DHCP server is available on the network, the Residential Gateway will automatically
get the IP address from the DHCP server. Otherwise (Disabled), the user needs to specify
the IP address, Subnet Mask and Gateway. When DHCP is used, the following items need
to be set as well.
