DHCP Server
You can disable or enable the DHCP (Dynamic Host Configuration Protocol) server or enable the
router’s DHCP relay functions. The DHCP protocol allows your router to dynamically assign IP
addresses to PCs on your network if they are configured to obtain IP addresses automatically.
To disable the router’s DHCP Server, check
Disabled
and click
Next,
then click
Apply.
When the
DHCP Server is disabled you will need to manually assign a fixed IP address to each PCs on your
network, and set the default gateway for each PCs to the IP address of the router (by default this is
192.168.1.254).
To configure the router’s DHCP Server, check
DHCP Server
and
click
Next
. You can then
configure parameters of the DHCP Server including the IP pool (starting IP address and ending IP
address to be allocated to PCs on your network), lease time for each assigned IP address (the
period of time the IP address assigned will be valid), DNS IP address and the gateway IP address.
These details are sent to the DHCP client (i.e. your PC) when it requests an IP address from the
DHCP server. Click
Apply
to enable this function. If you check “
Use Router as a DNS Server
”,
the ADSL Router will perform the domain name lookup, find the IP address from the outside
network automatically and forward it back to the requesting PC in the LAN (your Local Area
Network).
If you check
DHCP Relay Agent
and click
Next
, then you will have to enter the IP address of the
DHCP server which will assign an IP address back to the DHCP client in the LAN. Use this
function only if advised to do so by your network administrator or ISP.
Click
Apply
to enable this function.
