2nd Subnet - Select the router to change the RIP information of
the 2nd subnet with neighboring routers.
DHCP stands for Dynamic Host Configuration Protocol. The
router by factory default acts a DHCP server for your network so
it automatically dispatch related IP settings to any local user
configured as a DHCP client. It is highly recommended that you
leave the router enabled as a DHCP server if you do not have a
DHCP server for your network.
If you want to use another DHCP server in the network other
than the Vigor Router's, you can let Relay Agent help you to
redirect the DHCP request to the specified location.
Enable Server - Let the router assign IP address to every host in
the LAN.
Disable Server – Let you manually assign IP address to every
host in the LAN.

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
