Wireless-G Router for 3G/UMTS Broadband

DHCP Server Settings

The Router can be used as a Dynamic Host Configuration Protocol (DHCP) server for your network. A DHCP server

automatically assigns an IP address to each computer on your network. Select the mode you want the Router to

use for its DHCP server function. If you are not sure which mode to select, keep the default, Mode 1 - Fixed

configuration (Default).

Mode 1 - Fixed configuration (Default). In this mode, the Router will advertise itself as the DNS server for the

clients (computers) to use. The clients will contact the Router for DNS, and its DNS caching server will resolve the

addresses for them. This mode is recommended for networks whose UMTS upstream DNS servers change on a

connection-by-connection basis, such as networks in the UK.

Mode 2- Network Supplied. Via DHCP, the Router will advertise the DNS and WINS servers it is using. This mode

may be suitable for networks whose DNS servers have static addresses.

Mode 3- Manual configuration. You can designate the settings advertised to the clients via DHCP. Complete the

Static DNS and WINS fields that will appear. You can specify up to three DNS servers and up to two WINS servers.

Make sure these values do not depend on the Router’s static settings.

Network Address Server Settings (DHCP)

The settings allow you to configure the Router’s DHCP server function. If you choose to enable the Router’s DHCP

server option, you must configure all of your network PCs to connect to a DHCP server (the Router), and make

sure there is no other DHCP server on your network.

DHCP Server. DHCP is enabled by factory default. If you already have a DHCP server on your network, or you

don’t want a DHCP server, then click the Disable radio button (no other DHCP features will be available).

Starting IP Address. Enter a value for the DHCP server to start with when issuing IP addresses. Because the

Router’s default IP address is 192.168.1.1, the Starting IP Address must be 192.168.1.2 or greater, but smaller

than 192.168.1.253. The default Starting IP Address is 192.168.1.100.

Maximum Number of DHCP Users. Enter the maximum number of PCs that you want the DHCP server to assign

IP addresses to. This number cannot be greater than 253. The default is 50.

Client Lease Time. The Client Lease Time is the amount of time a network user will be allowed connection to the

Router with their current dynamic IP address. Enter the amount of time, in minutes, that the user will be “leased”

this dynamic IP address. After the time is up, the user will be automatically assigned a new dynamic IP address.

The default is 0 minutes, which means one day.
