the DHCP server to start with when issuing IP addresses. If
the 1st IP address of your router is 192.168.1.1, the starting
IP address must be 192.168.1.2 or greater, but smaller than
192.168.1.254.
IP Pool Counts - Enter the maximum number of PCs that
you want the DHCP server to assign IP addresses to. The
default is 50 and the maximum is 253.
Gateway IP Address - Enter a value of the gateway IP
address for the DHCP server. The value is usually as same
as the 1st IP address of the router, which means the router is
the default gateway.
DHCP Server IP Address for Relay Agent - Set the IP
address of the DHCP server you are going to use so the
Relay Agent can help to forward the DHCP request to the
DHCP server.
DNS Server
Configuration
DNS stands for Domain Name System. Every Internet host
must have a unique IP address, also they may have a
human-friendly, easy to remember name such as
www.yahoo.com. The DNS server converts the
user-friendly name into its equivalent IP address.
Primary IP Address -You must specify a DNS server IP
address here because your ISP should provide you with
usually more than one DNS Server. If your ISP does not
provide it, the router will automatically apply default DNS
Server IP address: 194.109.6.66 to this field.
Secondary IP Address - You can specify secondary DNS
server IP address here because your ISP often provides you
more than one DNS Server. If your ISP does not provide it,
the router will automatically apply default secondary DNS
Server IP address: 194.98.0.1 to this field.
The default DNS Server IP address can be found via Online
Status:
If both the Primary IP and Secondary IP Address fields are
left empty, the router will assign its own IP address to local
users as a DNS proxy server and maintain a DNS cache.
If the IP address of a domain name is already in the DNS
cache, the router will resolve the domain name immediately.
Otherwise, the router forwards the DNS query packet to the
external DNS server by establishing a WAN (e.g.
DSL/Cable) connection.
Force router to use address for DNS-
Force Vigor router
to use DNS servers in this page instead of DNS servers
given by the Internet Access server (PPPoE, PPTP, L2TP or
DHCP server).
