in the LAN.
Disable Server - Let you manually assign IP address to every
host in the LAN.
Relay Agent - Specify which subnet that DHCP server is
located the relay agent should redirect the DHCP request to.
Start IP Address - Enter a value of the IP address pool for 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 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.
Force DNS manual setting - 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).
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
