Vigor1000 Series User's Guide
Enable Server - 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.
You can configure the router to serve as a DHCP server for
the 2nd subnet. Check the box to enable DHCP server
setting.
Enable Relay Agent – Check this box to enable such
function.
Start IP Address- Enter a value of the IP address pool for
the DHCP server to start with when issuing IP addresses. If
the 2nd IP address of your router is 220.135.240.1, the
starting IP address must be 220.135.240.2 or greater, but
smaller than 220.135.240.254.
IP Pool Counts- Enter the number of IP addresses in the
pool. The maximum is 10. For example, if you type 3 and
the 2nd IP address of your router is 220.135.240.1, the
range of IP address by the DHCP server will be from
220.135.240.2 to 220.135.240.11.
Lease Time- It allows you to set the leased time for the
specified PC.
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
external DNS server by establishing a WAN (e.g.
DSL/Cable) connection.
