Internal DHCP Server
indicates that you have a DHCP server device on your network that
will assign an address to the port.
If you choose either the internal or external server option, the LAN interface is called a
DHCP client of the server.
Note
that the public IP address assigned to you by your ISP is not your LAN IP address.
The public IP address identifies the WAN (ADSL) port on your ADSL/Ethernet router to the
Internet. Or, in bridge configurations, it may be assigned to a PC.
z
Speed/Duplex:
Speed indicates the speed of the Ethernet communication between the
ADSL/Ethernet router and the LAN PCs or hub. Duplex indicates the type of Ethernet
communication (i.e., full duplex, or half-duplex). These settings are not
user-configurable.
z
LAN IP Address and Network Mask:
The IP address and network mask for the port.
z
IGMP:
Indicates whether this interface is enabled with the Internet Group Management
Protocol. When enabled, the ADSL/Ethernet router collects and consolidates requests
from the LAN PCs to receive IGMP messages from external computers. The interface
also forwards IGMP messages it receives on its WAN interface to the appropriate hosts.
The WAN interface must also be enabled for the IGMP protocol.
z
MTU:
The Maximum Transmission Unit specifies the size in bytes of the largest Ethernet
packet that the interface will accept. Packets larger than this size will be dropped.
5.3.2 DHCP
Mode
You can configure your network and ADSL/Ethernet router to use the
Dynamic Host
Configuration Protocol (DHCP)
. This help topic provides an overview of DHCP and
instructions for implementing it on your network.
