5.2.2 DHCP Mode

You can configure your network and DSL device to use the Dynamic Host Configuration Protocol

(DHCP). This page provides DHCP instructions for implementing it on your network by selecting the role

of DHCP protocol that this device wants to play. There are two different DHCP roles that this device can

act as: DHCP Server and DHCP Relay. When acting as DHCP server, you can setup the server

parameters at the DHCP Server page; while acting as DHCP Relay, you can setup the relay parameters

at the DHCP Relay page.

Max Lease Time

The Lease Time is the amount of time that a network user is allowed to maintain

a network connection to the device using the current dynamic IP address. At the

end of the Lease Time, the lease is either renewed or a new IP is issued by the

DHCP server. The amount of time is in units of seconds. The default value is

86400 seconds (1 day). The value

–

1 stands for the infinite lease.

gateway for your LAN hosts and for the DSL device provide the most appropriate

path for all your Internet traffic

DNS server

It is used to select the way to obtain the IP addresses of the DNS servers.

5.2.2.2 DHCP Relay Configuration

Some ISPs perform the DHC

P server function for their customers’ home/small office

network. In this case, you can configure this device to act as a DHCP relay agent. When a

host on your network requests Internet access, the device contacts your ISP to obtain the

IP configuration, and then forward that information to the host. You should set the DHCP

mode to act as a DHCP relay.
