DHCP Server Mode: DHCP Server
To configure the router‟s DHCP Server, check DHCP Server. 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 performs the domain name
lookup, finds the IP address from the outside network automatically and forwards it back
to the requesting PC in the LAN (your Local Area Network).
DHCP Server Mode: DHCP Relay
If you check DHCP Relay and then you must enter the IP address of the DHCP server
which assigns 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.
This feature is only where the DHCP server is on the WAN.
